I found the exact commit that causes this bug
http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-quantal.git;a=commit;h=8f53b5444a25b5be3bfe0164316f9bc7845279c9
drm/radeon: properly handle mc_stop/mc_resume on evergreen+ (v2)
BugLink: http://bugs.launchpad.net/bugs/1091251
commit 62444b7462a2b98bc78d68736c03a7c4e66ba7e2 upstream.
- Stop the displays from accessing the FB
- Block CPU access
- Turn off MC client access
This should fix issues some users have seen, especially
with UEFI, when changing the MC FB location that result
in hangs or display corruption.
v2: fix crtc enabled check noticed by Luca Tettamanti
