https://bugs.freedesktop.org/show_bug.cgi?id=98016 --- Comment #5 from Andy Furniss --- Also the way 4.9-wip changes and things get merged may not make bisecting a long way back that easy compared to something like mesa. I notice it's changed again 17 hours ago - it may even work now without you being able to see any sign od a revert or fix in the history. Maybe testing other branches (after power off of course) would give you a better idea where you are. -- You are receiving this mail because: You are the assignee for the bug.
