[Brad Figg <brad.figg@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.

We have noted that there is a newer version of the development kernel
than the one you last tested when this issue was found. 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-3.18.0-11.12

Title:
  Kernel Oops - unable to handle kernel NULL pointer dereference at
  0000000000000010; EIP is at fb_release+0x26/0x60

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  My laptop has a kernel problem with the Ubuntu 15.04 live disk.

  The Kernel reports constantly about a NULL pointer reference.

  Sometimes the X-server starts without the Unity interface and the UI freezes constantly for a few seconds.
  It often ends with a complete freeze of the computer.

  Other times the computer freezes before the desktop was loaded.

  I think it could be the radeon driver for my ATI Mobility Radeon HD
  5650.
