Bug description:
  SRU Justification

         The upstream process for stable tree updates is quite similar
         in scope to the Ubuntu SRU process, e.g., each patch has to
         demonstrably fix a bug, and each patch is vetted by upstream
         by originating either directly from a mainline/stable Linux tree or
         a minimally backported form of that patch. The v3.13.11-ckt36 upstream stable
         patch set is now available. It should be included in the Ubuntu
         kernel as well.



         The following patches from the v3.13.11-ckt36 stable release
  shall be applied:
