Anyone recompiled kernel/modules for x86_64?

[Ken Johanson <fedora kensystem com>]

Has anyone successfully recompiled their kernel + modules on an AMD 
opteron platform? When I try to boot I get various "module format 
invalid" messages and maybe even some kernel oops as I recall.

Here's roughly my procedure, for sanity checking :-)

cd /usr/src/linux<vers>
cp /boot/config-2.4.20-8 /usr/src/linux/.config
make clean
make oldconfig
make modules
make modules_install
/sbin/mkinitrd /boot/initrd-2.6.5-1.358custom.img 2.6.5-1.358custom
make bzImage
cp arch/x86_64/boot/bzImage /boot/vmlinuz-2.6.5-1.358custom
edit grub.cong adding the 'custom' kernel & initrd, then try to boot to it.


Thanks,
ken
