Updating to the latest drm-next-4.6-wip I could no longer log in to Gnome through GDM, I just got a black screen after entering my passwd. startx + gnome-session worked though.
Please attach the Xorg log and output of dmesg captured after getting the black screen.
Please also attach the output of glxinfo.
