Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 14.04 LTS
linux-image-3.13.0-61-generic - 3.13.0-61.100
linux-image-3.13.0-61-generic-lpae - 3.13.0-61.100
linux-image-3.13.0-61-lowlatency - 3.13.0-61.100
linux-image-3.13.0-61-powerpc-e500 - 3.13.0-61.100
linux-image-3.13.0-61-powerpc-e500mc - 3.13.0-61.100
linux-image-3.13.0-61-powerpc-smp - 3.13.0-61.100
linux-image-3.13.0-61-powerpc64-emb - 3.13.0-61.100
linux-image-3.13.0-61-powerpc64-smp - 3.13.0-61.100

To update your system, please follow these instructions:

After a standard system update you need to reboot your computer to make all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. If you use linux-restricted-modules, you have to update that package as well to get modules which work with the new kernel version. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-server, linux-powerpc), a standard system upgrade will automatically perform this as well.
