[Bug 59649] [r600][RV635] GPU lockup CP stall / GPU resets over and over - Kernel 3.7 to 3.12 inclusive

https://bugs.freedesktop.org/show_bug.cgi?id=59649

--- Comment #24 from Shawn Starr shawn.starr@rogers.com --- Using the following options caused GPU reset:

Option "ColorTiling" "true" # [<bool>] Option "ColorTiling2D" "false" # [<bool>] Option "RenderAccel" "false" # [<bool>] Option "AccelMethod" "exa" Option "EXAPixmaps" "True" # [<bool>]

Whats interesting also is the GPU resets, X hangs (doesnt recover) rebooting laptop will work but when grub finishes loading the kernel the laptop hangs as the GPU is in a bad state. I have to hard power off/on for it to work again.

Testing with ColorTiling2D only enabled now,
