When I was bitten by the infamous '-N' bug, it seems to me the 
exception I got said "UTLB" in it somewhere.  This one doesn't.
So maybe that's not the problem.

And I think I might be being bitten by the same thing.  All 2.4 
kernels I've tried die with what seems to be a similar error on 
my Indigo2 (R4400 200Mhz).  I thought I read somewhere something 
about XZ graphics causing problems and boards should be 
removed... why? Could this be the cause? I have XZ in my 
machine.... I want to try a few more things before sounding too 
many alarms though...
