LAva, could you please test the latest upstream kernel available from
the very top line at the top of the page (the release names are
irrelevant for testing, and please do not test the daily folder)
following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow
additional upstream developers to examine the issue.

If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-3.XY-rcZ

Where XY and Z are numbers corresponding to the kernel version.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-3.XY-rcZ

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results.

Thank you for your understanding.

Title:
  Kernel Oops - unable to handle kernel NULL pointer dereference at
  00000004; EIP is at drm_mm_remove_node+0x51/0xf0 [drm]

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  My laptop has a kernel problem with the Ubuntu 14.10 live disk.

  The Kernel reports constantly about a NULL pointer reference.

  Sometimes the X-server and the Unity desktop is started, but 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.

  This bug report was created with the information of the Ubuntu 14.10
  32bit live disk, but I also encountered the same problem with the
  Ubuntu 14.10 64bit live disk.

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