Josh and I had a curious problem that we diagnosed by hooking up  to  
the serial console and then turning the key over to the debug mode  
(or did we just boot with debug max)?

Turned out to be one of the CPUs that had a faulty something or other- 
it would start booting then throw a critical error.  Removing the CPU  
and replacing it with another one fixed the problem.
