   A data point - options DEBUG and/or options LOCKDEBUG makes the
   SIR problem go away.
   I seem to hit a sir instruction even before multiuser. I'm trying to 
   find out
   the offending instruction address, but the system tends to lock up 
   pretty hard.
   

from this 'ok' prompt type 'ctrace' - it will give you the stack
trace, including the offending pc...
