Yes.  Every time I upgrade I hope the problem will be fixed. :-)  If it's
a hardware problem, it's fairly prevalent.  I have 20 of these machines
and have seen the problem with others.  I have one on my desk and it
locks up more often.   The others are all headless and boot with
AlphaBIOS/MILO.  This one is SRM/aboot.  I tried swapping my desktop
with one of the others and had the same symptoms.

OK, I'll definitely do this next time.
