Solution

Please install the updates provided at the location noted below.

Installation notes

This update is provided as an RPM package that can easily be installed onto a running system.
First, find out which kernel package to download and use, for example with

rpm -qf /boot/vmlinuz

Download the kernel image fitting your setup and the kernel symbols (kernel-syms*.rpm) and install it with either:

rpm -Fvh kernel-syms*.rpm kernel-default*.rpm for the default kernel image, or
rpm -Fhv kernel-syms*.rpm kernel-smp*.rpm for the SMP kernel image with support for up to 64 GB, or
rpm -Fhv kernel-syms*.rpm kernel-bigsmp*.rpm for the SMP kernel image with support for up to 64 GB

Please do only install one of these kernels, not all of them.
In case you are using LILO as bootmanager, please make sure that you also execute the command

lilo

after installing the update for the system to remain bootable.
Finally, reboot the system with

shutdown -r now

to load the new kernel (replace "now" with the appropriate amount of time to allow local users to cleanly log out, for example "+5" for five minutes.)
