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 use, for example with
rpm -qf /boot/vmlinuz
Download the kernel image fitting your setup and install it with:
rpm -Fvh kernel-*.rpm
In case you are using LILO as bootmanager, please make sure that you also execute the command
after installing the update for the system to remain bootable. If you are using GRUB you don't need to do anything.
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.)
