Did the original post say that this machine had one cpu, and now it's
being upgraded to two cpus? I've found that for smp to work, both
processors have to have the same lot number. I recently upgraded a dual
pii300 to dual pii600. I wanted to make sure that my motherboard was ok
with the coppermine pii600. So I first bought one pii600. That worked
fine with a up kernel. Then I bought a second one, and the two cpus did
not work with an smp kernel. Actually, Linux wouldn't even boot. After
I exchanged one of the cpus to get a matching lot number pair,
everything worked under smp. Good luck,
