ACER TravelMate 8204 WLMI: suspend/hibernate does not power off the laptop

I tried again with kernel 2.6.22-13:

$ uname -a
Linux vougeot 2.6.22-13-generic #1 SMP Thu Oct 4 17:18:44 GMT 2007 i686 GNU/Linux

Results are slightly different but neither suspend nor hibernate does power off the laptop:

 - suspend locks the screen and then nothing happens. Il can unlock the screen and continue to use the laptop.

 - hibernate behavior is still the same as in kernel 2.6.22-12. I have attached a new kern.log with a hibernate attempt.

I'm getting very similar behavior with on an Acer Aspire 5102. The laptop never actually powers down. Prior to loading Ubuntu, this system could suspend to RAM and hibernate to disk with no issues (that was running Debian sid).

The problems remains with this kernel version:

Linux vougeot 2.6.22-14-generic #1 SMP Wed Oct 10 06:00:47 GMT 2007 i686 GNU/Linux

Is it possible this is the same as bug 133363 [0], with a fix here [1]? There is a is fix posted there, but I haven't been unable to test it yet due to some other complications. First off, module-assistant thinks that the name of the fglrx drivers source package is "fglrx-kernel-src," when it is actually "fglrx-kernel-source." Secondly, after extracting the sources by hand, the build fails.

Thank you for the hint! However it does not solve the problem. This problem is not related to the fglrx kernel module at all. Even if I boot the laptop without the fglrx module, the suspend/hibernate problem is still there. I applied this patch nevertheless because it may be useful to solve resume problems (wake-up from suspend/hibernate) if I ever manage to suspend/hibernate this laptop.

For the record, this problem still exists with the latest gutsy kernel version:

Linux vougeot 2.6.22-14-generic #1 SMP Sun Oct 14 23:05:12 GMT 2007 i686 GNU/Linux

ii linux-image-2.6.22-14-generic 2.6.22-14.46 Linux kernel image for version 2.6.22 on x86

I finally got around to trying this last night as well, using the latest
fglrx available from ATI. It did change the behavior of my system, as it
will now suspend and/or hibernate without just hanging, but when I try to
resume, the system seems to respond, but the screen remains dark and I have
to reboot.

I have the same issues when I try to hibernate my Acer 1694 laptop:the screen remains on black with a blinking cursor and the fan is still spinning...I'm using ubuntu gutsy with last kernel and I installed latest fglrx drivers.Thank you very much for your work!

I am assigning this bug to the 'ubuntu-kernel-team' per their bug policy. For future reference you can learn more about their bug policy at https://wiki.ubuntu.com/KernelTeamBugPolicies .

I installed kernel 2.6.24 from hardy and the problem is fixed:

 - suspend and hibernate do stop the machine
 - resume from hibernate does work
 - resume from suspend does work if I deactivate the fglrx kernel module

Therefore I believe that the problem will be fixed in hardy and I'm closing this bug. Thanks to the Ubuntu kernel team!

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.
