FreeBSD 6.1-STABLE: Unexplained power off

[Dennis Melentyev]

Don't take it personally, but could it just power-off the monitor?
What does show the disk activity led?

AFAIR, if you have to power-off manually (long pressing power button)
before power-on, it does will make FS dirty. Instead of real correct
power-off case.

Try to make a simple script appending some log/file with timestamps,
wait untill your issue occurs, then check the time, wait for, say, 5
more minutes and then cold-start system again.

I bet, the script will still be logging messages into the file while
system looks like "sleeping".
