Vitaliy reported that his system crashes when suspending to disk.
This
was a regression from 3.2 to 3.7, and remains in 3.8. Some details
of
this system are in the bug log at <http://bugs.debian.org/700333>.
The photo shows a BUG in hrtimer_interrupt() after making the
hibernation image and while resuming the non-boot CPUs. The HPET
interrupt handler was called immediately after it was registered for
CPU
2 (?), before the corresponding clock_event_device was registered.
Seems like an obvious race condition, but then shouldn't the HPET
have
been stopped while the CPU was previously offlined? And it's strange
that this system apparently hits the race quite reliably.
