RE: MMU problems?

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.

I have seen a lot of discussions about MMU on MPC823,

There are no MMU or cache related problems on any of the MPC8xx
processors and stable versions of Linux.  These are just people
discussing the challenges of building custom boards and making
source code changes.

There are dozens of people shipping products with Linux running on
these processors.  You seldom hear from people that are happy and
successful.

Yes, and it runs just like any other system that doesn't have any
swap space and a minimal amount of memory.  Some things just don't
work well, and applications fail because few test for memory allocation
failure.

Are there bugs?  Perhaps.  Do I want them fixed?  Yes.

Do you want to help this FREE software effort?  If you are so sure
there is an MMU bug, find it, fix it, and send me the patch.  We would
all be grateful.  If you want dedicated help to assist your custom
product development so you can make money, you may have to pay one
of the very capable embedded Linux companies for this attention.

Thanks.
