Yes, I need to find the right docs to decode the meaning though.
I've not been motivated to chase this lately.

A few more observsation about HPMC problems:
o A500-55 and A500-44 don't have this problem.
o SMP kernel on 1 CPU and UP kernel on the same box *should* do exactly
  the same things besides aquire/release spinlocks. This suggests someone
  fixed something in the non-SMP code path and missed the SMP part.

HP9000/800 series machines should all support <ctl>-B
to get to service processor prompt.
"he" for help.
"rs" to reset the machine.
"tc" to capture current state of the machine for debugging "hung" machines.
(TC data is available with "ser pim" output")
