I'm seeing different responses depending on hardware.

On regular Pentium 166 machines, I almost NEVER get
a panic.  On brand-new Pentium II 350s, I get a panic
every 6-9 hours.  This happens when both kernels are
configured the same for maxusers.  It happens when
both machines are under the same load level -- the
P5 stays rock solid, the P6 flakes out.

What's the chance that our kernel adaptations for PIIs
is partly at fault?
