Here is what I did to track down the errors.
I created a diff between the last working kernel 2.6.12 and the current
kernel. Started with cpu-probe.c, that to me seemed the logical choice.
After patching the rest of files needed to support the patch in
cpu-probe.c, I was finally able to produce a kernel under 2.6.12 with
the same problem.
The files that I ported from 2.6.14 to 2.6.12 are the following
cpu-probe.c
cpu.h
mipsregs.h
cache.c
cpu-features.h
Here is a link to the patches I used http://ftp.jg555.com/errors
Looking at mipsregs.h, something doesn't look right for a 64 bit system.
But I'm not the expert.
Here are my findings, I hope someone out there has an idea.
Stanislaw pretty much figured it out last night.
See the if statement in the 'void __init cpu_cache_init(void)' function in
arch/mips/mm/cache.c. IP30, IP27, and cobalt didn't define the appropriate
cache type in cpu-features.h, thus failed that check and panicked. I believe
it's fixed in the newest IP30 patches, of which I have yet to take a look at.
