Can you provide more details about these system freezes?  Some
questions:

 . What exactly freezes?  Can you start a new application, or move the
   mouse pointer, or ping the system from the net?

 . What do you see in /var/log/messages around the time of these
   freezes?

 . When it freezes, do you see the disk I/O indicator lit, indicating
   some disk I/O, or is the indicator off?

 . Any other relevant details.

Thanks.
