Status. I have two seemingly identical machines. I've been running
one with SMP and one without, and have swapped which is running
which. I have never seen a SP version lock up, but I have had 4
total lockups (3 on one host 1 on the other, but #1 has been running
several days longer), and one cpu1 lockup where cpu0 was still
running. Two of the lockups happened when the machine was essentially
idle, with xdm waiting for a login.
I don't have the motherboard model# handy right now but these are
the earlier version of the MSI 6501 Dual AMD Athlon MP - the one
without onboard USB. They were supposed to be the newer one...
looks like our supplier pulled a fast one.

I turned xdm off on one of them. Will see how stable it is without
