Where's the culprit?

[Peter King]

Culprit found! (I think.)

After some more testing and lockups, I swapped out the ethernet card. It then
rebooted, but crashed under heavy load. Upon the reboot, well, lo and behold, 
this showed up in dmesg:

... and so on, for some 45 repetitions, before the kernel declares that it's
initializing HighMem. So I think that nails it down: bad memory sticks. Back
to Canada Computers.
