/sys/class/drm/card0/error , hang triggered by chrome w/hw-accel on youtube
On a laptop with Intel Core i7-8550U and integrated UHD Graphics 620, I
experience frequent hangs when using chrome browser watching youtube or using
mpv to playback video.
If I disable use of hardware acceleration in chromium browser or force software
decoding/rendering in mpv, the crashes are way less frequent.
With hardware-acceleration enabled I almost immediately get a gpu hang in
chromebrowser when visiting youtube (starting a video is guaranteed to trigger)
Symptoms of hang differ from frozen image for a few seconds after which it
recovers (although next error then only is a few minutes away, until it reaches
a point where it cannot recover anymore), to complete freezes (still image
shown, audio loops the last couple seconds, no reaction to keyboard whatsoever,
cannot even use magic sysRq anymore) to crashes of Gnome3/wayland (can switch
to virtual console and login/trigger reboot)
Distro: Mageia (Cauldron/development)
kernel: 4.19.12
mesa: 18.3.1
chromium-browsser: 70.0.3538.77</pre>
