I am having the same lockup problems as Chuck with SMP kernels built since
October 21.  The system completely locks up after a short period of time.
If I'm running X, it does it within 10-15 minutes, but if I don't run X
and just leave it at the console, it can go for a few hours.  It does
eventually lock up, though.  I haven't tried building a UP kernel, but I
will try the latest vm_machdep.c changes.  If that doesn't work, I'll go
the UP route since I'm tired of being unable to list my processes.  :\

My working world+kernel was built October 4.  Normally, I update my
-current system more frequently than that, but this has been an abnormally
busy month.  Because of that, I can't narrow down exactly when the
instability began.  Right now, I'm running with a world built October 23
and the October 4 kernel which is rather unpleasant.
