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...
