You probably still have modules compiled for the previous kernel
sitting in /lib/modules.
If you are compiling different kernels from the _same_ kernel version
(i.e. both are 2.2.12 - never mind the -20, that's a RedHat thing),
then you cannot have modules for both kernels in the same
So, before doing 'make modules_install', either do
# rm -rf /lib/modules/2.2.12-20
# mv /lib/modules/2.2.12-20 /lib/modules/backup-2.2.12-20
and then do the 'make modules_install'.
Redhat's use of the -20 subversion at the end of their kernel
versions is part of their system to get around this problem.
I don't know exactly how it works as I haven't had the need to
figure it out. (I always recompile the kernel with the latest
stable version when I install a machine.)
