A badblocks scan turned up nothing, but that doesn't guarantee no-fault. 
I might run it overnight and see.

Again, it looked like nothing was sharing IRQs. While I do have a lot of 
NICs in there, there is no USB, serial etc so it's not too crowded in 
the end. That said, I like modern IO-APIC machines - my home PC's video 
card has IRQ 28.

Bill: the motherboard has no onboard sensors, alas, but the heatsink 
remains quite a manageable temperature. Also, would've expected a 
memtest86 to cause the CPU to overheat/fail if this were the issue.
