My story is the same as Jim's except I used 2.6.16.6 and a gcc 3.3.3

and runs just fine. When ipipe is enabled, I sometimes get the error
Jim received, sometimes the kernel just hangs. There is never a stack
trace on the console. I've tried ipipe versions 1.2-01, 1.2-03,
1.3-00, 1.3-02, and 1.3-03, all with the same results (either the
kernel hangs or I get the kernel BUG error).
I haven't been able to get the board to boot without using the
motorola patch.
I have tried building with ipipe-tracer, but this results in compile
errors (the tracer patch applies just fine). Here are the compile
errors when ipipe-tracer is enabled:

#
Philippe, can you comment on this? I do not have an PPC build
environment at hand.
I can't reproduce it here, but that does not mean much, since I can't
select the same setup anyway, due to the missing patch. Is the file
arch/ppc/ipipe-mcount.S listed as being compiled during the kernel build?
@Gary: Do you get the same error without the Motorola patch?

Philippe.
