Using 9.10 Karmic Final.

Kernel problem in 2.6.31-14-generic

Received this in apport in the notification area. This was after an unsuccessful suspend attempt. The machine entered suspend fine. I left it be for a day, and tried to wake it up, but it just sat with a deactivated display and did nothing, not even hard disk access. In order to restart, the machine required a hard reset, as in, holding the power button down.

As far as I know, my memory is good.

I did have this problem with suspend with Jaunty also. I think my hardware isn't fully supported.

Hibernate DOES work correctly, though. Worked in Jaunty, too.

A little about my hardware:

HP Pavilion m7500y
ASUS P5LP-LE (Leucite) Motherboard
Pentium D 820 2.8GHz
Nvidia 8500GT
Unknown 160GB SATA drive (Ubuntu), WD 160GB PATA Drive converted to SATA (Windows XP Media Center)
Atheros PCI Wi-Fi Card (now, I've had trouble with this thing in Jaunty with hard panics every few days and whatnot, but it doesn't seem to be bothering my in Karmic yet, I haven't had a crash since beta.)
Soundblaster Audigy 4 (not pro)
Saitek Cyborg Keyboard
Logitech MX Revolution
Various USB gadgets

Here is the oops on kerneloops.org: http://www.kerneloops.org/submitresult.php?number=869169

Expected: Suspend works correctly.

Actual: Suspend puts computer into a coma; needs hard reset. On the following boot, apport says there was a kernel problem.

ProblemType: KernelOops
Annotation: Your system might become unstable now and might need to be restarted.

I have same problem, on MSI ex600 laptop. Hibernation is working but suspend is not. the pc goes to sleep but can't resume, forces to use hard shutdown.
Very important bug

[That Bum (jzachariou)]

Indeed, this particular oops is the oops of the moment on kerneloops. Of the 982 oops occurrences, 921 are for this specific kernel, 2.6.31-14-generic. So that's 93%. Apparently, something went wonky in this revision of the kernel.

See, I'm no programmer yet, but I have pretty good computer problem deduction skills.

Here is my source. http://www.kerneloops.org/searchweek.php?search=suspend_test_finish%28resume%20devices%29

It's right on their front page too. I hope it gets fixed soon, I like suspend in Windows...

I was having the same problem with Karmic Beta, as well. I was hoping the upgrade to the Final release would have solved the issue.

Hi That,

The warning reported here typically indicates that it took longer for your system to resume from suspend than expected. I believe there is a 5 sec barrier which your system likely exceeded. Typically you'll see something similar to "PM: resume devices took 8.664 seconds" in your dmesg output when this happens. A patch to prevent this warning has been applied via bug 464552. As a result I'm marking this as a duplicate to bug 464552. Please continue to track this issue at that report. Thanks!
