ExpressCard34 slot not hotplugable after boot

Status changed to 'Confirmed' because the bug affects multiple users.

Same problem on a Thinkpad X200. Trying to load the acpiphp module after boot fails:

  $ sudo modprobe acpiphp
  FATAL: Error inserting acpiphp (/lib/modules/3.2.0-27-generic/kernel/drivers/pci/hotplug/acpiphp.ko): No such device

  $ uname -a
  Linux x200s 3.2.0-27-generic #43-Ubuntu SMP Fri Jul 6 14:25:57 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

The following fixed the problem for my USB 3 Expresscard (NEC uPD720200):

    sudo echo acpiphp >> /etc/modules:

Modify /etc/default/grub to have:

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pciehp_force=1 pciehp_poll_mode=1"

and run

    sudo update-grub

Now hotplugging works as expected.

I confirm that rduke15's workaround also solves the problem on my Thinkpad Z61m running Ubuntu 12.04. Thanks!

I also confirm that rduke15's workaround solves this problem on a Dell Studio 1555 running Ubuntu 12.04 :)

Workaround seems to solve the problem here too, Lenovo T520.

Workaround works great ! HP pavilion DV6164ea with ti-based firewire expresscard.

I'm using ubuntu 13.04 (Linux 3.8.0-23-generic #34-Ubuntu SMP Wed May 29 20:22:58 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux)
on a lenovo T420.

Trying to use an AKE USB3.0 ExpressCard (detected as 05:00.0 USB controller: Renesas Technology Corp. uPD720202 USB 3.0 Host Controller (rev 02))

The workaround does not work for me, after hotplugging the card this happens:

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.10 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Allright done that with (Linux 3.10.0-031000rc5-generic #201306082135 SMP Sun Jun 9 01:36:22 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux)

First I removed the workaround stuff, namely:

    sudo echo acpiphp >> /etc/modules:

Modify /etc/default/grub to have:

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pciehp_force=1 pciehp_poll_mode=1"

Result: Card is not detected when plugging it in after boot.

Now I wanted to check if the workaround helps, but

modprobe acpiphp
FATAL: Module acpiphp not found.

Plus my Computer won't boot when the card is inserted, log:

[ 0.869378] xhci_hcd 0000:05:00.0: xHCI Host Controller
[ 0.869382] xhci_hcd 0000:05:00.0: new USB bus registered, assigned bus number 3
[ 1.785834] tsc: Refined TSC clocksource calibration: 2292.554 MHz
[ 1.785840] Switching to clocksource tsc
 - here it hangs until the card is removed -
[ 13.253006] xhci_hcd 0000:05:00.0: can't setup
[ 13.253012] xhci_hcd 0000:05:00.0: USB bus 3 deregistered
[ 13.253076] xhci_hcd 0000:05:00.0: init 0000:05:00.0 fail, -19

Workaround doesn't worl for me either.

After hotplug dmesg says
[ 144.626651] pciehp 0000:00:15.3:pcie04: Card present on Slot(0-1)

but in lsusb my USB 3.0-card is still not listed.

[Expired for linux (Ubuntu) because there has been no activity for 60 days.]

I solved the problem of running too, but I have another problem: the Express card I connected the fan to cool the notebook, if I leave it attached and I try to shut down the notebook does not turn off, but restarts, while if I disconnect the notebook shuts down regularly.
How can I fix? mine is Ubuntu 13.04. Thank you.

For me too, the hot plug workaround doesn't and I can't use the card (uPD720202) in Ubuntu 14.10 like that

I have to retract my statement. I'm using a Lenovo x220.
Disabling "PCI Express Power management" (Config -> Power) via Bios resolves the issue for me. Before Ubuntu became unresponsive (like the card is throwing a lot of interrupts) after the *2nd* hot-plug, first one seems fine though. On AC or Battery did not change the behavior.

Also I noticed "ACPI FADT declares the system doesn't support PCIe ASPM" in dmesg, so I'm not sure this bug is even related. I leave it here for people who have similar issues :)
