MMU problems?

[Lucinda Schafer]

I agree. I believe we ARE dealing with a kernel bug, and it is particular to
the MPC823.

Let's hear some success stories--embedded units in production, running in
the field for days, shutting down power and rebooting with no kernel panics.
That may help convince me we are dealing with a hardware issue.

Have you tried to do complex operation on a 8xx board like compiling the
kernel. This operation
works well on a PPC740 board, but on a 8xx after a long time the kernel goes
in an unstable
state. Theses bugs are related to the 8xx MMU code.
