>Description:

Machine had been unattended for several days.  Upon turning on monitor
this morning I discovered that the machine had paniced/rebooted and
got stuck on fsck (manual intervention needed).

I have the core file if someone wants me to look at something in
particular.  A quick look showed:

putte:/var/crash# gdb -k /kernel.DEBUG vmcore.0

The crash occured at 00:15am.  The only activity ongoing then was a
scheduled newsrun (Cnews).

>How-To-Repeat:

Have only seen the problem once.  System uptime was around 7 days at
time of crash.
