Title:
  Kernel oops during movie play with vlc - freeze of screen

Status in linux package in Ubuntu:
  Expired

Bug description:
  I have both video and audio over HDMI. In the middle of watching a
  dvd-movie with vlc the screen froze but audio continued to play via
  HDMI. Also I was still able to connect with ssh to the linux-pc.

  Here is the syslog that was generated:

  After the oops I tried to get to a tty-console (to get rid of the
  frozen screen) with ctrl-alt-F1 but then also audio playback stopped
  and I got those syslogs:
