I was running fct2 yum upgraded to fct3 and then to fc1. I decided to do a clean install to see how the installer had improved. I have a seperate /home partition so I do this often. Since the fresh install, my computer will lock up to the point where it won't respond even to ssh. I then have to hard reboot. I have had problems with the 3d screensavers locking x in the past and I have "blank screen only" selected for this reason. I have found info in the /var/log/messages from when one of the lockups occured. The computer was not being used. I was logged into gnome with a terminal open, no programs running but fetchmail.
