Frank, I had a similar problem with 2.0.5R.
My situation was all based on my systems rebooting at 02:01:00 EVERY single
day. After much looking around, I found that this was when /etc/security was
being run via cron. I could run it manually and it was OK. If cron ran it,
the system would silently reboot.

It would reboot when it tried the check my CDROM. I realize that your
problem is not with CDROM drives, but maybe having a CDROM drive is
only the catalyst for a bigger problem that my system no longer exhibits due
to some other change that I made.

Try to see if it happens at the same time every day or perhaps in some sequence.
If so, check out the /etc/crontab file to see if there is something
being started when the system reboots.


Hope this helps....


Jerry
