Brett,
Can you build a debugging kernel (eg, config -g) and map that PC to a
source code line? Also, can you print out the return address from the
SRM console & map that to a symbol? Eg:
halt code = 5
HALT instruction executed
PC = fffffc00004e7988
>>>e ra
gpr: 1A ( R26) FFFFFC00003861D0
>>>
You can map things to symbols by running gdb on sys/compile/BLAH/kernel.debug
& looking at the address with a *0x prepended. From a normal shutown,
you will see this:

306 dumpsys();
307 }

309 /* Now that we're going to really halt the system... */
310 EVENTHANDLER_INVOKE(shutdown_final, howto);
311
312 for(;;) ; /* safety against shutdown_reset not working */
313 /* NOTREACHED */
314 }
This information could be very helpful.
