This also occurs with the mainline kernel version
4.6.0-040600rc6.201605012031.

As far as I can tell the dmesg output is identical, but I'm including it
below in case there's something useful in there.

Title:
  radeon GPU lockup when using VLC and Firefox

Status in linux package in Ubuntu:
  Confirmed
Status in vlc package in Ubuntu:
  Confirmed

Bug description:
  When playing a video with VLC and running Firefox at the same time,
  the radeon driver consistently (reproducibly) locks up and crashes on
  my machine since upgrading to 16.04. I'm using a Radeon HD 6870.

  This does not happen with other video players (totem, mpv). Tested
  with different video codecs and different window managers (gnome-
  shell, metacity).

  When VLC starts, the following message is printed to dmesg:

  [  102.379520] [drm:btc_dpm_set_power_state [radeon]] *ERROR*
  rv770_restrict_performance_levels_before_switch failed

  This is not the case with Totem.
  When Firefox is started, or if Firefox had been running in the first place, a few seconds later it locks up:
