I'm not sure if the issue goes away if I boot from the older kernel.
First of all, I'm not quite sure how to do that. Also, the bug isn't
always present when booting from the current version. I've successfully
booted it a few times, although the bug does reappear frequently.

Title:
  [Kernel-Oops] Kernel NULL pointer dereference at interrupt when doing
  Centrino clock stuff (drm_kms_helper)

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I booted up Ubuntu 13.04 which I updated completely as of yesterday, logged on, and then I got the following black screen, which I took a picture of with my camera because this happens every time I try to use Ubuntu, so I can't access the logs.
