I was tending toward hardware, after reading messages similar to:
I haven't tried the "f8002010 wector p" command mentioned yet. Other
messages also suggest memory problems. ".trap-registers" was mentioned as
a maybe useful OFW command.

In this case "Externally Initiated Reset" is an XIR. Not sure when it can
happen on a U60 though - hardware watchdog and CPU trap when traps are
disabled - maybe others?
