  • On encountering I/O errors on write, make sure we return -EIO.
  • Prevent kernel oops in ip6t_LOG (with ipv6 firewalling enabled).
  • Fix JFS resize bug on big-endian architectures.
  • New drbd module, version 0.6.13, fixes data corruption if secondary node fails during sync.

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 64 bit iSeries kernel image, or
  • rpm -Fvh kernel-ppc64*.rpm for the 64 bit PPC kernel image
Please do only install one of these kernels, not all of them.
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
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.)
