I see them under heavy load, but I'm not so sure anymore.
This time I got a PC address which was nowhere near locore.s and an  
nPC that didn't make any sense at all ( being PC + 0x10 with no branch  
anywhere near that could do this )
I need to read more about OpenFirmware's debugging stuff, maybe I was  
on the wrong CPU.

Also, is what OF reports as 'Watchdog Reset' always an SIR?

have fun
Michael
