Well, with the wait states enabled, it's *almost* stable.  Almost.
It still crashes randomly.  Crashes appear to vary directly with
time running; by 5 minutes, ls will dump core.  At about 30 seconds, I
can do anything.  Gak.

Not power cycle time; run time.  I suspect the MMU is misbehaved.  Or
one of my other chips.  Is there anything one needs to have replaced
to run with a Warp Engine?
