I just experienced a sudden reboot.
I am running -current SMP. Cvsup, make world, rebuild kernel 20000709.

The system was very lightly loaded. I was running emacs creating a
shell script. When the reboot happened, I was attempting to go up the
tcsh history chain. I pressed the up arrow several times and the
system froze for a few seconds and rebooted. It did not drop into the
debugger.
I have
options DDB
options KTRACE #kernel tracing
in the config.
After the 'world and new kernel on 20000709, I did a 'make world' on
20000710, testing stability. No problems, although the time increased
by an hour to 9 hours.
