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

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
