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.
I was tending toward hardware, after reading messages similar to: http://markmail.org/message/irop2we4mclu7eas http://markmail.org/message/iqalxxkv4bowksk2I 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.
I'll look at those. Also, is what OF reports as 'Watchdog Reset' always an SIR?
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?
I don't think the U60 has a watchdog. Maybe it's an ECC error? Somehow I doubt that though, booting with diag-switch? true and diag-level max didn't find anything funny. Too bad /memory doesn't have a selftest method anymore.
have fun Michael
