Amilo L1310G laptop fan stops at kernel load

Also on feisty, kernel 2.6.20-16-386, there is the same problem!

https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/124168

Yep, i have to be tweaking the files /proc/acpi/thermal_events/THRM the files trip_points and polling_frequency, changing the power.sh and so on for acpi events in order to make the fan starts automatically on ubuntu. Previously, we didn't have this problem at all, and it's the last problem (big one, besides the poor ati drivers) to make this laptop work like a breeze with ubuntu.

So, if I understand well, have you found a solution? I'm newbie with Linux OS, can you help me? thanks :-)

I just installed Hardy with the new Kernel and i have now the same problem. On Gutsy the fan at least was running (although permanent), but i could integrate a script to control the fan. Now not even this works...

I added the kernel versions that were mentioned as being affected.
Can anyone else implement the changes that Eversmann made to fix the problem?

I posted what i'm done to fix all the problems with the laptops and make it work on the wiki:
https://wiki.ubuntu.com/LaptopTestingTeam/FujitsuAmiloL1310G?highlight=%28l1310g%29

What i posted in the thread was old news, i finally tweaked an dsdt file to fix the problem:

Regards.

Thanks for the update, and thanks for the workaround.
I'll see what I can do about getting this bug marked properly.

The 18 month support period for Edgy Eft 6.10 has reached it's end of life. As a result, we are closing the linux-source-2.6.17 Edgy Eft kernel task.

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

All right, i'll take a look at it and report a new bug if it's necessary.

Thanks for the information ;-)

I bumped to this bug while installing to a friend: can't really test it. So eversmann, really appreciated if you can try it and report if it helps.

Also have an Amilo l1310g here. Tried with kubuntu beta with the 2.6.27-4 kernel. Fans will stay either
always on or always off apparently depending on the temperature at which the machine was started.

This bug seems to have been resolved upstream

http://bugzilla.kernel.org/show_bug.cgi?id=8049

With a vanilla 2.6.28-rc1 kernel and bios version 1.0F and adding the kernel boot option "acpi.power_nocheck=1" the fans will work properly.

Thanks MikkoD. I'm pasting the upstream git commit id's here and will reassign this to the kernel team. However, against 2.6.20 this will be closed as Feisty Fawn 7.04 has reached it's end of life - http://www.ubuntu.com/news/ubuntu-7.04-end-of-life . Thanks.

I've applied the upstream patches to the tree containing proposed intrepid updates. Could you please test and see if this resolves the problem?

The test kernel is located here:

http://people.ubuntu.com/~sconklin/69925/

Thanks!

Just to be clear, this is not yet approved for intrepid updates, that's just what I applied it to.

Yes, the fans work correctly with the test kernel

Thank you!

Well done! Does the status mean that Hardy will get a fix for this?

Awesome!!

I'll install an intrepid copy on a l1310g as soon as i see the new kernel ready to apply. Then i'll update the l1310g page on the wiki.

Thanks a lot for the work.

Here's a test kernel with the same patches applied against hardy, in case anyone would like to test that.

http://people.ubuntu.com/~sconklin/69925/hardy/

I can confirm, that the fan is also running correctly with the hardy test kernel.

SRU Justification - Laptop fan stops at kernel load

Impact: Fan stops and CPU overheats

Patch Description: Add acpi special handling (3 upstream patches)

Patches:
http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-hardy.git;a=commit;h=55d1c6812cf9b3e3ef8dc34d436e47dde9d35366

Test Case: See if the fan works. These patch sets have been tested on both intrepid and hardy

Thanks for the fast testing, it helped me move this one along.

Great! I posted the link for the person who had the original problem to try the Hardy version, will report later if it helped. Do the commits mean that it'll eventually be included in Hardy updates?

yes, this will be included in a hardy update

Accepted into intrepid-proposed, please test and give feedback here. Please see https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

The work around using the kernel switch acpi.power_nocheck=1 seems to work in kernel 2.6.27-11, but not all the time. About 1 in 10 boots the fan still does not come on and it heats up and shuts down. What can I do to be of assistance as I am desperate to move my laptop away from MS.

I suspect Tim meant to target this fix for the upcoming 8.04.2 release, not the far-off 8.04.4. Marking the Intrepid target against the no-package task invalid (the Intrepid target for the kernel is still the same.)

Can anyone comment if they've been able to test and confirm this is fixed with the kernel in hardy-proposed? @David Rando, since you are the original bug reporter, would you be able to test and confirm? I unfortunately do not have the hardware to test. We'd definitely appreciate any feedback before blindly pushing out a fix for Hardy without any verification. Thanks.

this has not yet been uploaded to hardy-proposed, so is not a candidate for 8.04.2; pushing back the milestone.

Hi.

I would be able to test it if i can download an image with the kernel loaded in it, because i don't have this laptop anymore (but my sister has it).

I think she has a version of mint installed. I'll take a look if it's based on hardy, load the proposed repository and see if i can test it from there.

either way, i'll post it asap the results.

Thanks for the effort.

I recently installed Hardy since there were other unrelated problems in intrepid. Have tested the kernels Steve Conklin provided for hardy and intrepid, also compiled my own from hardy-proposed git tree. Fans have worked correctly in all versions with the acpi.power_nocheck fix so far.

Accepted into hardy-proposed, please test and give feedback here. Please see https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

hey. i tried the the test kernel and all the commands and copying the dsdt.aml file on my laptop. its the L1310G with intrepid, but none of those things helped. still after a while of usage the fan goes off and cpu starts to warm... any ideas for this ? sorry for my bad english..

Could you be a little more excact? what to do ? i tried apt-cache search 2.6.27-11.25 and didnt find anything? or is it something else to do??

Tested successfully linux-image 2.6.24-23 from hardy-proposed.
Also intrepid kernel 2.6.27-11 works.

Thank you.

Unfortunately it seems that the fan does not work for me. (Amilo l1310g)
Tried with ubuntu 8.10 and kernels 2.6.27-13 and the standard 2.6.27-11

The fan turns off when the temperature is lowered and won't turn on afterwards.

I made the same experience. The fix worked on hardy but not on intrepid.

Please check you have the kernel option "acpi.power_nocheck=1" added for all kernel versions.
What bios version are you using? I´m using 1.0F.

I'm using 1.0F. I tried the option acpi.power_nocheck=1. Do I need additionally noapic, nolapic or noacpi kernel options, since the sound system stopped working. The sound did play, but there was crackling noise present.

Also the overall system responded a bit slow.

The only thing you should change to a default installation is to add the acpi.power_nocheck option.

I have had problems with sound and networking (b44 driver) with this machine on occasion, tough
not with either of the current kernels (intrepid and hardy). The sound and network issues have been present prior to the acpi.power_nocheck fix which leads me to believe these are unrelated issues.

The page is outdated at: https://wiki.ubuntu.com/LaptopTestingTeam/FujitsuAmiloL1310G
Don't change the dsdt.aml file. Also the laptop described there seems to be a slightly different model as I have firewire and don't have infrared. Also my wireless card is based on the rt2500pci chip and is the only thing not working properly at this time (upstream issue).
