This looks like it is what caused it to crash.
That narrows it down somewhat, but does not give us a clue at all :(
Is the box fully dead after the crash ?The host was online and I went away for awhile, when I came back the system
had rebooted on its own (as I lost all of my X windows/etc).
Hmm. Did you have panic_timeout set ?
Hi,
No, I do not use panic_timeout or any type of watchdog that would reboot
the system upon a lockup/crash.
