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 install by using the following command:
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 -Fvh k_itanium2-smp-*.rpm for the Itanium2 SMP kernel image, or
  • rpm -Fhv k_itanium2.rpm-*.rpm for the Itanium2 kernel image, or
  • rpm -Fhv k_smp-*.rpm for the SMP kernel image
Please do only install one of these kernels, not all of them.
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.)
