Once again, the Xorg server is frozen displaying the last frame, and 
cannot be killed - one must SSH in to the machine from the network,
and do a 'poweroff' and press the power-on button to regain control
of the terminal - the VT-switch keystrokes (ALT+F[1-8]) do not work.

Title:
  radeon GPU lockup CP stall

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu 14.04.1 LTS

  I was working on a project and had the following applications open

  MySQL Workbench
  Google Chrome
  gnome-screenshot

  All of a sudden everything freezes, the indicator-multiload stopped moving.
  I was able to switch to tty1 using CTRL+ALT+F1 (see foto of the screen in the attachments)

  The error reads:
  radeon 0000:01:00.0: GPU lockup CP stall for more than 84744msec
  drm:radeon_cs_ib_fill *ERROR* Failed to get ip !
