[OpenAFS] openafs kernel module on Fedora Core 6 [Load Failure]

[Mike Polek]

There is a "bug" (undocumented feature?) in the FC6 installer.
It installs the i586 kernel by default, even when all the
older installers would detect that you had a machine capable
of using the i686 kernel.

On the install media, There should be a
Fedora/RPMS/kernel-2.6.18-1.2798.fc6.i686.rpm file.
Normally, you would NEVER use -U for a kernel rpm,
but in this case, you actually want to replace your i586
kernel with the i686 version.... so ...

rpm -Uvh kernel-2.6.18-1.2798.fc6.i686.rpm

and you might need to use --force at the end of that if it
complains.

Double check that your grub.conf has the right stuff.
I don't think it should actually change, but I always check
it for safety. When you reboot, you should have the i686
kernel. You can then load your i686 module.

Worked for us here.

Optionally, you an also just download an rpm for the newer
2.6.18-1.2869.fc6 kernel (or whatever the latest
and greatest is at the moment) for i686, install that, and
build an openafs kernel module for it. That's what we're
using now.
