That's presuming you have version 2 or 3 PROMs.  If you do then you can
get lots more information.  Do a `ctrace' and record the output.  You
should get something like this:

Type  'go' to resume
{f} ok ctrace
PC: f00581f0 
Last leaf: jmpl  f0058744    from edd00890 
     0 w  %o0-%o5: (f0000000 14 f0000000 0 2 0 )

call edd19f70    from edd18064

????     from edd08820 
     6 w  %o0-%o5: (0 0 0 0 0 0 )

jmpl  0    from edd2bce8      
     7 w  %o0-%o5: (0 0 0 0 0 0 )

{f} ok 

Do the same thing with `.registers'.  Then reboot the system and use gdb
on the kernel image.  

Take the `from' addresses and use the `disasem' command to find out what
functions those are.  Then correlating that with the wources you should be
able to get a really good idea why you're at the PROM.

Unfortunately I don't think the older PROMs are this useful.
