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 . 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.
