I hate to mention the obvious, but is CONFIG_X86_64_SMP set in the kernel? Other possibilities: CONFIG_USE_GENERIC_SMP_HELPERS=y CONFIG_GENERIC_SMP_IDLE_THREAD=y CONFIG_SMP=y CONFIG_HAVE_TEXT_POKE_SMP=y -- Bruce -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
