--- Comment #32 from Alexandre Demers alexandre.f.demers@gmail.com --- Created attachment 70223 --> https://bugs.freedesktop.org/attachment.cgi?id=70223&action=edit Partial kernel.log

Here is a partial kernel.log tracking what is going on at boot with some debug printk in evergreen_mc_stop() and evergreen_mc_resume(). Strangely, only one crtc is saved as enabled in the _stop function, but four are restored in the _resume function. Pretty sure it's not the problem we are looking for, but it is abnormal since only one crtc should be restored on resume. This is a bug by itself showing a problem in the save(stop)/restore(resume) mechanism.
