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

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

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.
