show_stack_overflow() doesn't have a debug case which follows frame
pointers. I shall submit a patch for this presently, and put it into
XenServer in the hope of getting a better stack trace in the future.

There is nothing apparently interesting preceding the crash. Just some
spew from an HVM domain using the 0x39 debug port.

The machine we found this crash on is a Dell R310. 4 CPUs, 16G Ram.
The full boot xl dmesg is attached, but it appears that the are 8
broadcast hpets. This is futher backed up by the 'i' debugkey (also
attached)
Keir: (merging your thread back here)
I see your point regarding IRQ_INPROGRESS, but even with 8 hpet
interrupts, there are rather more than 8 occurences of
handle_hpet_broadcast() in the stack. If the occurences were just
function pointers on the stack, I would expect to see several
handle_hpet_broadcast()+0x0/0x268
