kernel bisected. Here is the culprit commit from what I see here:
62444b7462a2b98bc78d68736c03a7c4e66ba7e2 is the first bad commit

    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?
