I own a dual Xeon 2.8 Ghz with HTT on and I don't have stability problems 
with 5.3-REL running.

It does have problems with the SCSI controller though. The problems it's 
having has something to do with the driver of the controller and not the 
fact that it's a dual Xeon or has HTT set on or off.

through my ALU.  I've asked for it to be replaced, but nobody ever

log out again.
