--- Comment #11 from Eugene Grosbein <eugen@freebsd.org> ---
It seems I've got same panic today on different server running system built
from same sources but completely different hardware: AMD Athlon(tm) II X2 2=
45
Processor vs. Intel(R) Xeon(R) CPU E5620 etc. Its FreeBSD configuration is
pretty same.

Can't tell for sure, though, because this system ran without any watchod
enabled and it hang hard at midnight. It has no console attached and was
power-cycled after weekend (it serves small office). Nevertheless, I suspect
same problem but this time it panices and failer to reboot all by itself.

I've just enabled on-board watchdog and watchdogd:

amdsbwd0: <AMD SB600/SB7xx Watchdog Timer> at iomem
0xfec000f0-0xfec000f3,0xfec000f4-0xfec000f7 on isa0

And will restart it with INVARIANTS-enabled kernel.
