Description Gene Czarcinski 2003-12-09 19:22:43 UTC 
Description of problem:
I have two systems with Fedora Core installed (fresh installes) and
all are "up to date".

The first system is a dual processor P-III.  I have not seen the
problem on this system.

The second system is a dual processor Athlon 2800+ on a Gigbyte
GA-7DPXDW-P motherboard.

I have had at least four solid hangs of my system (requiring hardware
reset).  At first, I thought it might be some GL screensaver since I
have had such problems in the past.  However, the last hang occurred
while was typing into a terminal window.  When I tried to ssh into the
hung system from a different system, it would not connect.

There is nothing in /var/log/messages.

Any tips on debugging this would be appreciated.

It happened again.  I am starting to see a pattern ... that is IIRC
each time this has happened.

This last time I had mounted a floppy (as root).  When I tried to
umount the floppy, that is when the system hung/froze.

IIRC correctly, I was doing a umount each previous time.
