The loader is copied to 0x600000 and execute from there ( I've reserved 4M for the boot + zImage + initrd).

The caches are enabled as far as I can tell from the code. I got the sources from the MontaVista site and applied the CPU6 patch you posted earlier. Apart from that, a couple of changes to mbxboot/head.S to set the IMMR and the UPM. > > > C00FF71B C00B8474 C00B8648 C00FA2B4 C00F7774 C000221C > > What is the rest of this backtrace? > C00FF71B buf C00B8474 extract_entropy C00B8648 get random_bytes C00FA2B4 init_elf_binfmt C00F7774 start_kernel C000221C start_here Daniel ** Sent via the linuxppc-embedded mail list.
