Symbol names would help. But I think you should find MIPS experts
who can help you sort out the low level problem. Try linux-mips or

able to help. (Maybe)

I'll have a look.

Register dump is good, but..

This doesn't mean much.. Enable the option to include the symbol
table in the kernel for oops printouts.
