I agree w/David. Have you tried turning on the CPU_FTR_NEED_COHERENT? Take a look at include/asm-powerpc/cputable.h and search for the reference to CONFIG_PPC_83xx. Even if that solves the problem we need to figure out of there is an errata or what that causes this to work. - k _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
