197b:2381 [Acer Aspire 5930] JMicron internal card reader recognizes SD only when inserted at startup

lspci -vvnn output with SD card inserted at boot time. Note that all of the JMicron related items are missing if the SD card is only inserted after booting.

Forgot to mention: this is on Intrepid alpha 4 (x86_64), uname -a:

Linux razor 2.6.26-5-generic #1 SMP Sun Aug 10 20:28:44 UTC 2008 x86_64 GNU/Linux

same laptop - same problem

Please note XD card is not recognized even if you put it at boot...

On
http://www.linlap.com/wiki/acer+aspire+5930
it says
[you have to add “modprobe pciehp” in ”/etc/rc.d/rc.local”]

But I'm not sure where to add "modprobe pciehp"
Is it /etc/rc.d
or
/etc/rc.local

adding it to /etc/rc.local made no change

As per http://packages.ubuntu.com/search?searchon=contents&keywords=pciehp.ko , that module is only available on the -i386 kernel flavour.

Regards,
maykel

The pciehp module is compiled into the kernel for Jaunty:

ogasawara@yoji:~/ubuntu-jaunty/debian/config$ grep -rn "CONFIG_HOTPLUG_PCI_PCIE" *

amd64/config:1103:CONFIG_HOTPLUG_PCI_PCIE=y

i386/config:1175:CONFIG_HOTPLUG_PCI_PCIE=y

lpia/config:1045:CONFIG_HOTPLUG_PCI_PCIE=m

@Benni, since you are the only one who has mentioned using a 2.6.28-11 Jaunty kernel, can you attach the following:

 * sudo lspci -vnvn > lspci-vnvn.log
 * dmesg > dmesg.log

Can you also confirm the original issue mentioned in the bug description:

"the reader is only listed by lspci if the SD card is present in the reader at boot time. Boot time dmesg attached.

Now if an SD card was present at boot time, I can remove the SD, and dmesg will report

[ 164.613053] mmc0: card db81 removed

If I reinsert it, dmesg will say

[ 179.271670] mmc0: new SD card at address db81
[ 179.276522] mmcblk0: mmc0:db81 SD512 500224KiB
[ 179.276522] mmcblk0: p1

and gnome will display an SD drive icon on my desktop and ask if any files should be imported.

But nothing of all that happens if the SD card was not already in the card reader at boot time!
Update description / tags".

Thanks.

hello. I'm using Ubuntu Jaunty (9.04), fully-updated..

[~] uname -a
Linux gil-laptop 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:57:59 UTC 2009 i686 GNU/Linux

without inserting card at boot time I have:
[~] lspci -vvnn > lspci_-vvnn_[without_card_at_boot].log
[~] dmesg > dmesg_[without_card_at_boot].log
and nothing happens when I'm insert and release card.

with inserted card at boot time I have:
[~] lspci -vvnn > lspci_-vvnn_[with_card_at_boot].log
[~] dmesg > dmesg_[with_card_at_boot].log
and card-reader works fine.

Alexander 'gil' Tarasov was faster :D

but you have x86_64 :)
post your "lspci -vvnn" & "dmesg" too.

Great, nobody will solve this bug....

Try that: http://www.arsgeek.com/2007/04/30/get-your-ricoh-sd-card-reader-working-in-ubuntu/ . I have to find my old file, but I think that's what I did to solve the problem.

the module you posted doesn't work in my case (Aspire 6920G). Same issues as without the module. maybe it's another module?

True, it doesn't seem to work anymore.

The same problem (SD card not recognized if not inserted at boot time) is cropping up on my Acer Aspire One with kernel 2.6.31-1-generic. Note that the problem does not occur with the current Fedora Rawhide kernel (2.6.31-0.38.rc1.git7.fc12.i586)

so a solution is already 'indirectly' available... if fedora kernel has a working SD management...

Is this fixed in karmic?Seems like the problem is coming from the older kernel version.
Fedora uses a newer kernel( I think).
I am experiencing the problem with my Acer 5737Z laptop

Same problem with Acer 5730zg laptop...

Bug still occurs in karmic (aspire 6920, 2.6.31-6-generic). At least an xd card still isn't recognized, don't have an sd card to try with.

wondering if this bug can be fixed... it's so boring switching to vista just to download content from the xd card..or having to reboot just to do the same it when equipped with SD... :\

no it is not fixed in karmic x64 with all latest updates, still same problem card will not mount unless int he slot before booting, dont see why you should have to switch to vista, just reboot with the card inserted bit of extra pain but works until a solution comes along.

Confirm the same bug on my Acer 5737Z laptop Karmic x64.

Here is my lspci -vvnn attached

@dream.coder: and what about XD card (it's not a smile, XD)...? I can only access it through vista...

On Acer Aspire 5930G with Ubuntu 9.10 x64 the SD Card Reader don't work.
Hope to get it working on near future ;)

Still present in Lucid with 2.6.32-5-generic on amd64.

no way to solve this bug soon...

Confirming that the bug is present in lucid as well

my internal reader should read xd cards. it doesn't. this problem has been around for a year and a half. wtf guys. wtf.

please assign this to someone, this is an annoying hassle to deal with, and there are a lot more jmicron readers out there now. it should be a priority.

get your shit together, this is ridiculous.

It seems no one suggested this workaround. I'm running Archlinux on a Acer Aspire 5930G like the original poster, so your mileage may vary.

I added the line:

options pciehp pciehp_force=1

to the file /etc/modprobe.d/fix-the-jmicron-sucker.conf and rebooted.

Now I can hotplug my SD card and have them recognized without a hassle.

For reference, I'm running 2.6.31 in 64bit

Sadly this didn't work for me

SD cards worked out of the box for me on my mini9. XD cards still don't. This is something that should have been fixed a while ago, yet there isn't even someone assigned to it.

Sadly, this doesn't help for Acer 6935G, even for SD card.

Default kernel has pciehp built-in, not as a module, so modprobe.d wouldn't help by default. Though, grub boot options didn't help either.

If pciehp was built as a loadable module, it would be easier to try it.

#42 unfortunately doesn't for me, either

no good news from lucid side?

add the kernel parameter pciehp.pciehp_force=1 and be on your way

Found that in #371434, maybe it can help some of you:

>Would the subscribers of this bug please try booting with kcmdline pciehp.pciehp_force=0 and then "sudo modprobe acpiphp" ?

booting with pciehp.pciehp_force=0 and then "sudo modprobe acpiphp" doesn't work for me :(

For this card reader to work on Acer laptops (that is the subject of this bug) we must force its unmask with the kernel parameter pciehp.pciehp_force=1 as Steven said (not force=0, that is counter productive), but then the computer won't suspend with a card mounted; to correct this follow the instructions found in the wiki page for the Aspire One: https://help.ubuntu.com/community/AspireOne/Ubuntu9.10, the Aspire One has a Jmicron card reader as well.

So the hack workaround exists, but it's a hack workaround in fact, I'm not expert enough to say wether it's the optimal solution. I've read somewhere that this card reader has power management that is lost with the force on option.

No success here with pciehp.pciehp_force=1 on kernel cmd line :-(

dmesg gives:

Bernhard, I checked with SD, MS and micro MS+adapter on Aspire 5930g, which kind of card were you trying to mount?

SDHC

Thanks a lot to ceg!!! Now I have working properly my JMicron card reader on my Acer 5737z even if the card is not inserted during boot time.
Nevertheless all tests were done with SD and microSD cards, other type of cards must be test additionally
Here is a little workaround:
1. Remove all parametr pciehp.pciehp* from /etc/default/grub (grub2)
2. Update your grub2 config: update-grub2
3. Reboot
4. Insert module acpiphp to kernel "sudo modprobe acpiphp"
5. Try to insert card to cardreader.
6. You can add string to /etc/rc.local before string "exit 0" to automaticaly loading this module during startup.

[wados@acer:/]$ cat /etc/rc.local
#!/bin/sh -e
# By default this script does nothing.

modprobe acpiphp
exit 0

I think I have found a workaround, though I have only tested it on debian.

I have done the following.

1. Create a file /etc/modprobe.d/aspire-fix-sd-slots.conf with the following contents:

options pciehp pciehp_force=1 pciehp_slot_with_bus=1
install sdhci for i in 2381 2382 2383 2384; do /usr/bin/setpci -d 197b:$i AE=47; done; /sbin/modprobe --ignore-install sdhci

2. Then add the following lines to /etc/modules:

pciehp
acpiphp

3. Modify the following line from /etc/default/grub:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

so the result is this:

GRUB_CMDLINE_LINUX_DEFAULT="pciehp.pciehp_force=1 elavator=noop quiet splash"

4. Then issue an update-grub as superuser (eg: sudo)

My system is:

alex@io:~$ uname -a
Linux io 2.6.32-3-686 #1 SMP Thu Feb 25 06:14:20 UTC 2010 i686 GNU/Linux

I know that pciehp loading at boot time gives an error with pciehp_slot_with_bus=1

pciehp: Unknown parameter `pciehp_slot_with_bus'

but perhaps it is due to my system and this option is available on other systems.

Hope it works as well on Ubuntu systems!

I am adding some more details about my system:

Acer Aspire 5737Z

Hi All

I just test on my laptop (Compaq Presario CQ41), It doesn't work.

Having no luck here on Lucid, SD card detected and mounts no problem, if inserted upon boot, XD Card won't even detect.

I'm seeing this exact problem with Lucid on an Aspire One AOA 150Ab and an SD card.
A variant on #61 works for me - I only needed #1 and #2.

Having this issue with a lenovo ideapad y450 (uses a jmicron card reader) running lucid 10.04

If a sd card is inserted at boot it registers like so:
Disk /dev/mmcblk0: 3965 MB, 3965190144 bytes
49 heads, 48 sectors/track, 3292 cylinders
Units = cylinders of 2352 * 512 = 1204224 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000

        Device Boot Start End Blocks Id System
/dev/mmcblk0p1 4 3293 3868160 b W95 FAT32

But if its inserted after boot the device doesn't show up in fdisk -l.

Oh, and the fix from post #61 doesn't fix it, I'm getting:

mmc0: error -110 whilst initialising SD card

whenever I insert a card after boot.

dmesg says:

[ 300.502275] mmc0: card claims to support voltages below the defined range. These will be ignored.
[ 300.502282] mmc0: host doesn't support card's voltages
[ 300.502296] mmc0: error -22 whilst initialising SDIO card

#61 doesnt help.
ubuntu maverik 10.10 2.6.35-22-generic

any ideas??

on ubuntu maverik 10.10 2.6.35-21-generic & ubuntu lucid sd-card was working

regards maik

edit:

dmesg on 2.6.35-21-generic says:

[ 3.555780] mmc0: new SDHC card at address d555
[ 3.558489] mmcblk0: mmc0:d555 SD08G 7.60 GiB

this means that the same card work on the same notebook with another kernel. ^^

3. Compile drivers with root permission
   # make
   # make install

This issue has apparently also been posted to the kernel bugzilla at https://bugzilla.kernel.org/show_bug.cgi?id=16119 -- but unfortunately, kernel bugzilla is currently offline due to some recent attack on the kernel hosts.

My laptop (Compaq CQ41), After upgrade OS to be Ubuntu 11.04.
The problem was solve every thing works find.

I'm using Aspire 6920, and this was an historical bug. I found a workaround by rebooting with the SD card just on the slot.

BUT now I've upgraded to 11.10 and the workaround does not work anymore!

dmesg does not detect anything after inserting the SD on the slot.

I'm using the 64bit version.

If it is a trouble around kernel setup there is a way to rebuild it with the right module?

In HP Pavilion dv4-2014la and HP Pavilion dv6-1238es, it seems that is a problem with a BIOS configuration. Disabling the Card Reader Energy Saving in BIOS makes the JMicron card reader works without booting with a card inserted.

Thanks to Alejandro Martin Jimeno, i finally solve this problem.
i did most as Alejandro Martin Jimeno said.

In 1st step, i created the file "/etc/modprobe.d/aspire-fix-sd-slots.conf", but i just added the content:
options pciehp pciehp_force=1
into it.

In 2nd step, i appended the content:
pciehp
acpiphp
jmb38x_ms
sdhci-pci
to /etc/modules. i think it is used to load the module automatically when the os starts. In my opinion, jmb38x_ms and sdhci-pci are the drivers for JMicron card reader. For my sd card, only if i add sdhci-pci and jmb38x_ms into /etc/modules, the sd card could be detected as soon as the sd card is inserted.

For other cards, like xd, i think you should recompile the modules as the instruction at http://ubuntuforums.org/showthread.php?t=1718934#10, and add these:
flash_bd
xd_card
jmb38x_xd
into /etc/modules.

I also finally solved this problem, but on an Acer Aspire One AOA150 netbook.
I followed fortime's instructions and these worked for me. The earlier form of these instructions did not work for me.
I only have an sd card to test it; I have not tested with an xd card.

Thanks

I should have added that this works for me under Ubuntu 12.04

This bug is fixed for me in Ubuntu 12.04. My computer is HP Pavilion dv4-2014la

The bug is still there for my Acer Aspire 5951 under 12.04, kernel 3.2.0-24-generic-pae.
The PCI slot appears only when booting with a card inserted.
Fortime's workaround didn't work but I have to say that I cannot manually load acpiphp for an unknown reason ...

I too had this problem and manage to solve it with disabling the powersave for the card reader in the bios..., people with problems should try ti

Solved as FORTIME said.
I added all of the following, and after reboot, it showed uSD:

pciehp
acpiphp
jmb38x_ms
sdhci-pci
flash_bd
xd_card
jmb38x_xd

No need to recompile new module

Bernhard Reiter, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the mainline kernels archive directory daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.7-rc1-quantal

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

Please let us know your results. Thank you for your understanding.

Hello, I have the same issues on a Dell XPS L702X laptop and I recently found out in the Ubuntu forums that the following command forces a pci rescan and if a card is inside already then it is recognised. Tested only with an SD card.

echo 1 > /sys/bus/pci/rescan

Tasos Gropalis, if you have a bug in Ubuntu, the Ubuntu Kernel team, Ubuntu Bug Control team, and Ubuntu Bug Squad would like you to please file a new report by executing the following in a terminal:
ubuntu-bug linux

For more on this, please see the Ubuntu Kernel team article:

Please note, not filing a new report would delay your problem being addressed as quickly as possible.

Thank you for your understanding.

I frankly didn't feel like testing this again with every new Ubuntu release like I did in the first years (!) after I first posted this bug without any evidence about upstream changes that might have actually solved this issue. However, the upstream bug report linked from this one suggests that kernel 3.12 and later might contain an actual fix for this bug -- that would include Ubuntu 14.04 LTS "Trusty" which is going to include 3.13 (or even 3.14). If someone else affected by this bug and subscribed to this bug report could test it under Trusty because they're already running the development version/Beta, please report here if it's fixed there. (Otherwise, I'm going to upgrade to Trusty shortly after its release and report here if it works for me then.)

Upgraded to Trusty. Still not working.

Okay, I'm amazed. Updating the BIOS *did* indeed fix my issue!

I might've started the party too early.

Now the SD is back to not working unless inserted at startup. Maybe last time I hadn't really shut down but rebooted from a state in which I had the SD inserted before, and that lead to a false positive.

Bernhard Reiter, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-3.15-rc4

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.

Still not fixed in 3.15-rc8.
