Hi,

Last night when I was asleep my FreeBSD workstation suffered a kernel panic 
and did a coredump. The panic occurred at 3.02 AM, that is one minute after 
the start of the daily script (coincidence?).

The only "unusual" thing I have been doing before the panic was that I was 
playing with a 1GB USB Flash memory stick. I found out that in order to 
create a partition on the device, I need to make it slightly smaller than the 
maximum suggested by sysinstall (I used sysinstall to partition the device 
out of pure lazyness). However, I think the panic occurred a couple of hours 
later and the USB media was not mounted at the time  (not 100% sure but I 
think so), so I don't think it is related but I can be wrong.

The system was built with CPUTYPE?=p4 from a cvs(up) snapshot of the 
RELENG_5_4 branch taken sometime on Wednesday April 20th.

best regards,

Viktor


Here is the backtrace that I obtained from kgdb:
