Description of problem:
I have upgraded from RH 7.3 to 8.0 and since then when I log out from user to
the login screen the GDM (or maybe it is the X windows) freezes sometimes and
sometimes causes the computer to restart.
Recently I am having problem to get to the login manager at the first place and

Expected Results: needless to say.
I'm having the same problem!. Aprox 1/3 of the times, after logging out from my KDE session, the Xserver or something freezes, and I have to hard-reset my computer. Some times the computer resets itself.

/var/log/messages using the link below. Also attach the output of "lsmod"

Please note that last week I could not start the X server any more so I had to
reinstall a clean copy of RH 8.0. Apparently it did not solve the problem.
