kernel bisected. Here is the culprit commit from what I see here: 62444b7462a2b98bc78d68736c03a7c4e66ba7e2 is the first bad commit commit 62444b7462a2b98bc78d68736c03a7c4e66ba7e2 Author: Alex Deucher alexander.deucher@amd.com Date: Wed Aug 15 17:18:42 2012 -0400

drm/radeon: properly handle mc_stop/mc_resume on evergreen+ (v2)

- 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

So it may not be the same bug I'm hitting as Serkan is. Where should I track this faulty commit/bug? In the NI CAICOS bug or in a new one?

That indeed looks like a separate bug to me, so I suggest to open up a new bug.
