2.6.32-22-generic kernel breaks suspend/resume on Thinkpad X60s

[Philip Armstrong]

suspend/resume works fine with 2.6.32-21-generic, but suspend never completes with 2.6.32-22: the screen blanks and the system hangs; the suspend light never stops flashing & it won't resume.

OK, addendum: suspend/resume fails with 2.6.32-21-generic as well. I was confused by the fact that suspend/resume *does* work if you try it from the initial gdm login screen: once you've logged in once, it will always fail thereafter (whether you're logged in or not). I was just rebooting into the older kernel & trying it, not actually logging myself in.

I've tried the 2.6.34 kernel from the ubuntu kernel ppa & the Karmic kernel as well & they all fail. Now, suspend/resume definitely used to work on this laptop. I'll try the earlier kernels & see if any of them work.

Hi Philip,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

OK, I'm afraid I don't know whether this is a kernel bug, or whether it lies elsewhere. I can at least confirm the following:

1) Booting from a Lucid install CD, suspend and resume work perfectly
2) Using the same kernel as the LiveCD (2.6.32-21.32) on my X60s install fails to suspend.
3) The latest 2.6.34 release from the kernel ppa also hangs.

Both the Install CD & the X60 install are using the same xserver-xorg-video-intel version (2:2.9.1-3ubuntu5).

Any ideas where else I could be looking?

[Philip Armstrong (phil-ubuntu)]

Oh, and suspend/resume work perfectly from the gdm login screen. It's only after login that they start to hang. Maybe the wireless drivers are hanging? I'll have a prod.

[Philip Armstrong (phil-ubuntu)]

Ah ha! Found the culprit: it's the SD card slot.

If there's an SD card mounted, then suspend hangs. Unmount the SD card before suspending and everything works perfectly.

I guess this is pm-utils bug #137810 again then. Re-assign?

[Chris Skalenda (chris-atld)]

I doubt it is the same bug, as this is new behavior with lucid on the X60. I'm pretty sure it worked in previous releases.

I'm glad you found the culprit. I've been frustrated by this bug for months! :)

[Philip Armstrong (phil-ubuntu)]

searching on sd card suspend reveals that this is an ongoing problem with a number of laptops. Bug #569882 is a report on a Thinkpad X61 (very similar hardware to the X60) for instance, but there are a number of others with laptops from a variety of manufacturers. I wonder if they're all using the same SD card hardware?

Glad to have helped you anyway Chris :)

@Philip Armstrong -- good job!!!

Jesus Christ, I've been bothered by this problem for months! It started like half way through beta (iirc). I've been hoping someone can iron this out. I'm going to mark this bug as a dupe, because obviously we know now with absolute certainty how malicious and awkward this bug can be. I wonder how many other people are affected by this that are looking to solve the problem in all the wrong places.

I consider myself pretty seasoned, but I couldn't find any trace of the cause of this no matter how hard I looked.
