kernel-2.6.30.5-43.fc11.ppc64 problems - back out kernel?

[bjlucier]

After installing:

Sep 8 15:39:43 localhost yum: Updated: kernel-firmware-2.6.30.5-43.fc11.noarch
Sep 8 15:40:25 localhost yum: Installed: kernel-2.6.30.5-43.fc11.ppc64
Sep 8 15:41:09 localhost yum: Installed: kernel-devel-2.6.30.5-43.fc11.ppc64
Sep 8 15:41:11 localhost yum: Updated: kernel-bootwrapper-2.6.30.5-43.fc11.ppc
Sep 8 15:41:17 localhost yum: Updated: kernel-headers-2.6.30.5-43.fc11.ppc

I'm getting hit with the kernel oops reported here:

https://bugzilla.redhat.com/show_bug.cgi?id=516218

which was reported against 2.6.31 rawhide (not 2.6.30) and closed since the fix was merged upstream.

I would like to back out the 2.6.30 kernel installs and avoid the delays on startup waiting until the machine boots with one of the older kernels. Is there a way I can safely do this?

The old kernel should still be on the system, it keeps 2 by default.
When you see the kernel line hit esc and you will see the other kernel line.

Once booted up, download the old kernel rpm parts (firmware, bootwapper headers), the other (devlel) is still there.
Then
rpm -Uvh kerenl-...rpm kernel....rpm kernel...rpm --oldpackage --test
if no errors.
rpm -Uvh kerenl-...rpm kernel....rpm kernel...rpm --oldpackage

reboot into the old kernel again.
then remove the new 30 parts
rpm -qa kerne*
rpm -e kernel-30 kernel-30-part1 kernel-30-part2 ... # from -qa list.
