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 kernel-iseries64.rpm for the iSeries64 kernel image, or
  • rpm -Fhv kernel-ppc64.rpm for the PPC64 kernel image
(Note: only install one of these kernels, not all of them).
The kernel sources can be installed using the following command:
rpm -Uvh kernel-source.rpm
After performing the RPM package update of your kernel package, you
must execute the following commands as root to make sure that your
system will start up again:
mk_initrd
lilo
Note: If you do not execute the commands above, your system might be
in an unbootable state. To ensure that the fixes become active, you should
reboot your system usingthe command
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.)
