Strange. In just the past few, 2 or 3 or even 4 weeks my
Dell-8200 has spontaneouslyrebooted too. I do have a number of
things in /var/log/messages, but nothing that I can seee that
would cause this problem. Before the video-card started flaking
out, this puppy ran for weeks/months happily. AFAIW, X (or a
heavily-loaded system) shouldn't have aynything to do with this
problem, [yes/no??]. Any clues, Garrett?
