RedHat 8.0 SMP kernel system freeze

[David . Koert]

Just installed two new Dell PowerEdge 2650 servers: dual Intel Xeon 2.0 GHz processors, 5x drive SCSI RAID (5).  Self-installed RH8.0.  Systems run for about 4 hours then completely freeze - no messages in log files after boot-up.  If we run single processor kernel everything is fine.  We can't recall ever having seen linux freeze up like this before.  Any thoughts?
