Update Instructions

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

Ubuntu 16.10:
  linux-image-4.8.0-1038-raspi2   4.8.0-1038.41
  linux-image-4.8.0-54-generic    4.8.0-54.57
  linux-image-4.8.0-54-generic-lpae  4.8.0-54.57
  linux-image-4.8.0-54-lowlatency  4.8.0-54.57
  linux-image-4.8.0-54-powerpc-e500mc  4.8.0-54.57
  linux-image-4.8.0-54-powerpc-smp  4.8.0-54.57
  linux-image-4.8.0-54-powerpc64-emb  4.8.0-54.57
  linux-image-generic             4.8.0.54.66
  linux-image-generic-lpae        4.8.0.54.66
  linux-image-lowlatency          4.8.0.54.66
  linux-image-powerpc-e500mc      4.8.0.54.66
  linux-image-powerpc-smp         4.8.0.54.66
  linux-image-powerpc64-emb       4.8.0.54.66
  linux-image-raspi2              4.8.0.1038.42

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.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
