I would suspect either bad hardware,a flakey SCSI driver, or a possible 
kernel bug.  If your system is freezing hard, it is NOT postgresql's 
fault.  It simply doesn't have the access to the kind of system resources 
needed to freeze a machine.

Is there a different SCSI driver / card you can try in there?  We've (and 
many others have too) had good luck with the LSI/MegaRAID cards and both 
the older 1.18 seris and new 2.x series drivers.  No freezes, no crashes, 
no hangs on the boxes with those in them.
