Was busy up to now, and weekend also quite full already. Thing is: I didn´t see this blank screen thing with 4.8-rc6 so far. And I did not have above EDID stuff in my log either. So I first wait whether I see blank screen again and if so, then know that a test would make sense. Maybe I see it before I complete a rc7 or rc8 (if there will be one), then I would include the patch of course. -- Martin _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
