[Joseph Salisbury <joseph.salisbury@xxxxxxxxxxxxx>]

Thank you for taking the time to file a bug report on this issue.

However, given the number of bugs that the Kernel Team receives during
any development cycle it is impossible for us to review them all.
Therefore, we occasionally resort to using automated bots to request
further testing. This is such a request.

  With the recent release of this Ubuntu release, would like to confirm
if this bug is still present. Please test again with the newer kernel
and indicate in the bug if this issue still exists or not.

You can update to the latest development kernel by simply running the
following commands in a terminal window:

    sudo apt-get update
    sudo apt-get dist-upgrade

If the bug still exists, change the bug status from Incomplete to
Confirmed. If the bug no longer exists, change the bug status from
Incomplete to Fix Released.

If you want this bot to quit automatically requesting kernel tests, add
a tag named: bot-stop-nagging.

 Thank you for your help, we really do appreciate it.


** Changed in: linux (Ubuntu)
       Status: Confirmed => Incomplete

** Tags added: kernel-request-3.13.0-24.46
