--- Comment #9 from Thomas J. Moore darktjm@gmail.com --- Just thought I'd mention that 4.8-rc2 and 4.8-rc3 are still worse off than before, even though both have changes for amdgpu power management (i.e., no fix for this, and X still won't start any more, although I suppose maybe the later is because I'd need a matching update to xf86-video-amdgpu I'm not aware of). I won't report any further lack of progress.
