[lug] automatic reboot with RH 7.1

[Bowen Zhou]

Hi folks,

My problem is that my machine (Dell Precision 530, with RH 7.1) got
suddenly automatic rebooting roughly about once a week, and kick me out
gdm once every day! It drives me crazy, especially sometimes I am running
simulations! Following is some exception from the /var/log/messages. Could
you guys give me some clues about that?

Many thanks...
Bowen
