Description Bill Chatfield 2000-10-05 23:17:37 UTC
My system locked up completely while it was doing nothing but running the
screen saver.  This is what was in /var/log/messages.

This is the standard single processor kernel and kswapd that comes with
RHL7.

If there is any more information that I can collect to diagnose this
problem, please let me know and I'll try to get it.

It was caused by a hardware problem.
