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 either:

rpm -Fvh k_deflt.rpm for the default kernel image, or
rpm -Fhv k_smp.rpm for the SMP kernel image, or
rpm -Fhv k_numa.rpm for the Numa kernel image

(N.B.: only install one of these kernels, not all of them.)
If you need the kernel sources you can install them by using the command:


rpm -Uvh kernel-source.rpm

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.)
