I had some interrupt problems with the rtl8139 ethernet card in this SMP
system earlier (with 2.2 kernels), but that went away after I switched over
to an intel card.  I get no problems with a 2.2 kernel - except that USB
stuff doesn't work...  Then again, I can't get a bunch of USB stuff without
the system dying this way either, so I guess that's not overly important...

I took my 400MHz celerons down from 564 to 548, figuring that would be
enough to cure any overclocking-related issues.  Maybe I'll increase the
voltage, or redirect the logs to /dev/null... :)
