Am I missing something? > Can you look at the 'running' kernel's config to see if it's indeed the one you compiled (provided you enabled support for it during building - see /proc/config.gz)? Eg something like 'CONFIG_X86_64=y' is set. Is the machine you're building on 64-bit or 32-bit? I hope you used a 64bit compiler for building your kernel.
