1. Important general info
These kernel release notes are generic for all SLES 9 based products, so some parts may not apply to a particular architecture/product. In unobvious cases the respective architectures are listed explicitly. These release notes do not stick strictly to the kernel changes but also prospects to related fields and SUSE Linux Enterprise Server 9 Service Pack2 in general.
1.1 Purpose
This SUSE Linux Enterprise Server Service Pack serves multiple purposes:
  • Contains enhancements to the SLES 9 code base (see chapter 2 for kernel related parts).
  • Contains all maintenance fixes (see chapter 3), which were released since GA of SLES 9.
  • Provides an easy update of your system or individual packages to the latest Service Pack level. This is especially useful if you can not use online update mechanisms.
  • Provides improvements for an easy fresh installation using the latest kernel, drivers and updates to the installer.
  • Include PTFs (special fixes for customers) which were folded back into the common code base making them maintained.
  • Contains useful additional information and documentation.
Through joint testing and maximum care we try hard not to break any ISV certification with a Service Pack, but we recommend that you doublecheck with your ISV about the certification status of your application.
2. Enhancements
2.1 Installation
  • Added detection support in hwinfo for new/updated hardware drivers (see 2.2)
  • Updated reiserfs to version 3.6.19
  • Several LVM and resize fixes in yast2-storage

  • Added dialog to allow assigning PCI IDs to drivers This enables us to submit additional PCI IDs to a driver to enable the use of the devices utilizing the new PCI IDs: In case the driver was released before the related hardware, the support functionality is also warranted in the majority of the cases. Afterwards this information will be used during the installation but will also persist in the installed system.

3. Maintenance fixes

via the maintenance Web since the GA version. See chapter 4.3 how to install
these and chapter 7 where to find detailed documentation for each patch.
3.2 Security fixes
Service Pack 2 contains all the latest security fixes for each package
released via the maintenance Web since the GA version. See chapter 4.3
how to install these and chapter 7 where to find detailed documentation
for each patch.
4. Multiple Kernels
It is possible to install multiple kernels side by side. This feature is meant
to allow administrators to upgrade from one kernel to another by installing the
new kernel, verifying that the new kernel works as expected, then uninstalling
the old kernel. While YaST does not yet support this feature, kernels can
easily be installed and uninstalled from the shell using rpm -i <package>.rpm.
For information about managing packages from the command line, refer to the
Administration Guide.
The default boot loader menus contain one kernel entry. Before installing
multiple kernels, it is useful to add an entry for the extra kernels, so that
they can easily be selected. The kernel that was active before installing a new
kernel can be accessed as vmlinuz.previous and initrd.previous. By creating a
boot loader entry similar to the default entry and having this entry refer to
vmlinuz.previous and initrd.previous instead of vmlinuz and initrd, the
previously active kernel can be accessed.
5. Known problems
  • SGI Altix and Silicon Graphics Prism systems (ia64) SGI recommends PROM 4.20 or subsequent versions for all SGI Altix and Silicon Graphics Prism systems running SLES9 SP2. The updated PROM contains key bug fixes, along with support for new kernel features, such as memory error recovery. The latest PROM firmware can be obtained from SGI Supportfolio(TM): Caveat: PROM 4.20 and subsequent versions are not compatible with SLES9 SP1 or earlier kernels. If you want to switch between SLES9 SP1 and SLES9 SP2 kernels, DO NOT upgrade the PROM on your system.
  • For S/390 and zSeries For Installation more than 256 MB is needed.
  • For x86_64 For update to SP2 more then 256 MB are needed.
  • For Intel x86 and x86-64 CPUs Prior to SP2, the microcode update init script was disabled by default; normally the script should be enabled to allow for fixes to be applied to the microcode of Intel x86 and x86-64 CPUs. The default has been changed in SP2, so the microcode updating will be enabled on new installations. However, on old installations where SP2 is applied as an update, the script will not be enabled if it was disabled before. We recommend to enable it by issuing the command "insserv microcode" on the command line of a root shell or by enabling it in the YaST runlevel editor.
  • Using SCSI or hotplug devices may lead to boot failure or mount problems On reboot, SCSI or hotplug devices may be assigned to different device file names than before. If the root filesystem moved to a different device name, the kernel will not find it and fail booting. Workarounds: For a root filesystem use mount by volume label, see below. For all other filesystems configure mount by UUID using YaST2:
    • In YaST2 go to the Partitioner
    • For every SCSI device partition /dev/sd? with a mount point, go to Edit... -> Fstab Options and select Mount in /etc/fstab by UUID.
    Using mount by volume label for root filesystem:
    • Assign a volume label to the root filesystem and activate mount by volume label Go to the YaST2 Partitioner. Select the root filesystem (Mount on /) and go to Edit, then Fstab Options. Check Mount in /etc/fstab by Volume label. Enter a label in the field Volume Label, e.g. rootvollabel. Be sure to use a volume label that is not used by any other volume in the system. Commit changes (press Ok, Ok, Next).
    • Set up the root= kernel parameter in the bootloader configuration Go to the YaST2 Boot Loader Setup. Press Edit Configuration Files. In the line that starts with append =, add root=LABEL=rootvollabel to the kernel command line. rootvollabel is the Label you assigned to the root filesystem above. Commit changes (press Ok, Finish).
  • Detection of systems which always operate in physical APIC mode doesn't work yet

Installation notes

This update is provided as an RPM package that can easily be installed onto a running system by using this command:
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 install it with either:
  • rpm -Fvh kernel-syms*.rpm kernel-default*.rpm for the default kernel image, or
  • rpm -Fvh kernel-syms*.rpm kernel-64k-pagesize*.rpm for the 64k page size kernel image, or
  • rpm -Fhv kernel-syms*.rpm kernel-sn*.rpm for the SGI SN2 (Altix) 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.)
