I saved the following XMON dump...  (already had it enabled and it
dumped me there when the crash occured.)  I have translated it for you.
But I don't have the PC or LR.  I will have to recreate the failure
later tonight after I get off of work.

Also I used this line "sysmap=/boot/" to load the system
map but then I realized you said OpenFirmware path.  How do I calculate
the openfirmware path to the system map?  And would this be dynamic when
I recompile if I just put the file in the filesystem or would I have to
reload it with ybin?  Thanks again for all your help.

Here is the stack trace from "cat /proc/ioports":


Thanks again,
