Using pm-suspend from sys-power/pm-utils, my laptop suspends fine until about the tenth time, and then it fails to suspend, returning to the system after several tremulous seconds. Reproducible: Sometimes Steps to Reproduce: 1. pm-suspend 2. turn system back on 3. goto 1. until suspend fails Actual Results: System continues to run (apparently fine). Expected Results: System goes into sleep/suspend mode.

I just tried to attach the dmesg output, but it failed, perhaps due to using the backup server, so I'll wait and try again tomorrow or something. Or I could paste it into a comment, but it's pretty long, ~200 kB.

Have you tested with a gentoo-sources-2.6.28-r4
(In reply to comment #3) > Have you tested with a gentoo-sources-2.6.28-r4 > No, but I expect it will be the same result as other 2.6.28 kernels. See bug #257487. I can't test with 2.6.29 yet because x11-drivers/ati-drivers is not compatible with it yet. I just updated to 2.6.27-r10, so I'll see how that goes.
Haven't experienced this bug after a few days of suspending and resuming, so it's looking good! I didn't get around to creating a script to actually keep count, so I'll just wait a few more days before I close this bug.

(In reply to comment #6) > > So, Jeremy, how is it going? 2.6.27-r10 did the trick? > I _think_ so. I have the vague feeling that it may have happened once since I upgraded to 27-r10, but that's nothing compared to what was happening before. Anyway, I'll close it for now, and reopen it in the future if needs be.
I'm presume that this is the same bug, so I'm reopening it and changing the summary to reflect what I now know. The bad news is that it still exists. The good news is that I think I know why! My laptop has a couple of network fileshares mapped that are shared from my desktop. If my desktop is switched off and the laptop still has the shares mapped, then it is much more likely (though not certain) to fail to suspend. So that's where the problem seems to be, but it's difficult to be certain. I guess my next question is whether that is actually normal behaviour! Should a system suspend if there is a problem with fileshares? Maybe. Anyway, there is clearly a bug in this case, because dmesg is filled with call traces.

Jeremy, have you tried the latest development gentoo-sources release (2.6.32-r1)? Does the problem persist there too?

Created attachment 217709 [details] dmesg, 2.6.32, failed suspend
Created attachment 217711 [details] dmesg from 2.6.32, but only 1 task failed to freeze
Can you please add kernel parameters nohz=off highres=off to your grub line for kernel 2.6.32 and test to see if the failure occurs?
Created attachment 220123 [details] 2.6.32-r1, nohz=off, highres=off, dmesg and pm-suspend.log Still crashing. Is this debugging output actually helpful? Are there any other kernel debugging options that I can enable to make it more helpful?

This does not appear to be from 2.6.32, can you test with vanilla-sources-2.6.32.8 Linux version 2.6.31-gentoo-r6 (root@nx8220) (gcc version 4.3.4 (Gentoo 4.3.4 p1.0, pie-10.1.5) ) #4 Thu Feb 4 11:06:24 EST 2010 KERNEL supported cpus: Intel GenuineIntel
Whoops. :)
Actually, I 'whoopsed' too soon... a is from .32, but yes, b was accidentally .31.
Ok, try with the latest vanilla, and if that fails, please test with the atest development kernel, which is git-sources-2.6.33_rc8-r3 as of this writing.
Hi Mike, umm, with all due respect, is there any reason why it would actually be different in the next version? As you can see from the history of this bug, when I reported it about 2.6.27 you said "Have you tried 2.6.28?" So although I appreciate that bug reports are most relevant when they pertain to the latest version, I don't have much faith in the bug magically disappearing in 2.6.n+1. So, I will go ahead and test with 2.6.28.8, but is there something more focused that we can do? I can't risk running release candidate kernels, sorry.
PS. Should I keep using nohz=off and highres=off for testing?
Yes, you should take this upstream at http://bugzilla.kernel.org
Finally bothered to find the upstream bug.
