Everything is showing up as "Nominal" status.  
One note that might make a difference:
The system is a Dual Opteron - not single.  I was going by dmesg
output (and since GENERIC is non-SMP...), not on what I had actually
ordered (or LOM status showed ;-).

Also, isn't segfault usually only indicative of hardware failure when
it does not reliably occur at the exact same spot?

I should mention that this box was running some fairly intensive
network management software under Windows 2003 server for a month or
so solid as well - which would make me lean away from hardware
faults...

Any suggestions as to what to change HT settings to - or if that's a
worthwhile avenue to go down?

Thanks again,
