Oh, ick.  you might want to try 2.6.  2.4 is so crusty (but I do have
2.4 working on my virtex boards, so it's not unusable).  :-)

What's probably happening, is some code is trying to access device
registers after the MMU is turned on, but before ioremap is called on
the registers.  I've had this situation before.  I usually just trace
through the boot path to find out how far it gets before the trap so I
know which device driver is at fault.

If you can access memory, it's also useful to look at the contents of
__log_buf after the crash.  That will tell you approximately how far
boot proceeded.

Cheers,
