The things work better on our board now. The main problem, with 8xx kernel patches are spread everywhere, and kernel like mpc8xx contains a lot of useless changes that make the changes difficult to resync with the main serie. Kernel like 2.2.16 works properly and reliably on PPC7xx and PPC6xx processors, with a lot of PCI drivers functionnal now. I think the main effort will be to resync 8xx kernels with the standard ones. Now I have a patched 2.2.16 kernel that seems to work on our board. Complex operations like compiling a kernel take hours to complete on a 8xx board, and the bugs seems to have a low probability. (With the classic mpc8xx kernel, the system crash after only 20 minutes while compiling a kernel) I have some success with theses kernel now, but I'm not sure if some bugs remains, testing this system takes now hours... And this is quite undebugable... Patrick LERDA

Have you tried to do complex operation on a 8xx board like compiling the kernel.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. -- Dan
