Since your running through klogd, this might not be 'exactly' where you
die.  I would be TERRIBLY surprised if you died here.  One thing you
have to remember about kernel debugging is that you can't always trust
what is in the log.  Here is a technique that works for me when I'm
unsure of a piece of code:

Additionally, on PPCs, you have another technique, which is to use
prom_print or xmon_printf() (the latest one support full printf semantics
while the first one only supports a simple string).

xmon might really be helpful, but the crash is after the X server blanks the
display, so I wonder if xmon output would be visible?


Thanks to Jeff and everyone for the tips on how to debug this BTW.
