https://bugs.freedesktop.org/show_bug.cgi?id=80419 --- Comment #135 from Alassane Maiga --- I had something interesting happen with kernel 4.7 rc5 and mesa 12.1 git1591e66 The system would lock up, and the console would fill with the stalling ring messages. But then it won't lock up and will recover somewhat. The game wouldn't crash either, allowing me to exit it cleanly. Plasmashell would crash though, and there is a lot of video corruption on the desktop afterwards until the reboot. Happened two times in a row -- You are receiving this mail because: You are the assignee for the bug.
