I have some ideas. There are some "generic" functions doing some lazy processing that isn't likely to be valid on the 8xx, in particular the way demand zero pages are handled. Anyway, that's as far as I've traced it. Sometimes it appears to work, but it could be that what is happening still isn't correct, it just doesn't crash/hang. There are few other things that caught my attention where we used to execute generic PPC MM code without any ill side effects, but when these were ported to 2.6 we are now doing the wrong things on the 8xx. We just have to work our way though it with some applications and testing. -- Dan ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
