Using the newest beta driver 364.12, running mpv/mplayer causes a hard lock of the computer after opening window and showing 1 frame of the video. Even Alt-SysRq combos don’t work. So the only way is a hard reset, which no logs survive… but it’s not a kernel panic because keyboard leds don’t blink, really a hard lockup!
