So could it be a RAM ECC failure or some such?  What is supposed to happen
after an ECC failure?

I think so.  I have been watching the amount of "free" memory and after 12
days, it was still around 350 MB - and then suddenly the system died again.

There are around 150 interrupts per second, I guess this is pretty normal.

I'll attach both NetBSD and Xen dmesg outputs.

Yep.. :-(

I removed the second CPU I installed just before the problems started to
see if that helps.  I also installed another 4 GB of RAM and upgraded from
NetBSD 4.0 to 5.0, so I can't really tell which of the changes is to blame.
Before the upgrade, the system was running happily for 1.5 years.  (Yes,
I have heard it - "if it works, don't touch it".)
