    Subject2.6.22-rc1 does not boot on VIA C3_2 cause of X86_CMPXCHG64
    Hi,

    my small VIA C3_2 box does not boot with 2.6.22-rc1.
    It even does not uncompress the kernel.

    The configuration as M386 M486 works. But M586 + MVIAC3_2
    does not work.

    solution for me, cahnge arch/i386/Kconfig.cpu

    config X86_CMPXCHG64
    bool
    - depends on !M386 && !M486
    + depends on !M386 && !M486 && !MVIAC3_2
    default y

    The related #ifdef is in ./include/asm-i386/cmpxchg.h
    May be cmpxchg8b is not supported by VIAC3_2 ?

    May be some other non Intel/AMD need to be excluded from X86_CMPXCHG64 ?
    May be the generic option CONFIG_X86_GENERIC need to switch this off also ?


    Just write an email to me if you want to send a patch to test on a C3_2.

    Best regards,

    Christian
