Public bug reported:
At first, I didn't think there was a problem, because Ubuntu talked
about "a serious kernel problem" and I didn't notice anything wrong. But
now I see that the process 'ksoftirqd/0' has 100% CPU usage, while it
didn't, before I suspended.
The default summary was: 'WARNING: at
/build/buildd/linux-2.6.31/kernel/power/suspend_test.c:52
suspend_test_finish+0x80/0x90()'.
ProblemType: KernelOops
Annotation: Your system might become unstable now and might need to be
restarted.
