--- Comment #1 from bgrfdkt.x.loki04 at mamber.net ---
I have 
[drm] stuck on render ring
everytime I start Youtube Videos in Chrome in Full screen, sometimes when I
start Videos in Windowed Chrome mode. It is reproducable. Screen goes blank,
sound keeps playing. Screen only returns when I hibernate and re-wake the
laptop.

I guess the driver crashes on every use of hardware-acceleration.  


I have a HP Compaq 6710b Laptop with i915 graphics with Ubuntu 14.04.3 LTS
which worked perfectly until recently somethings where updated. Now I have
xserver-xorg-video-intel Version 2.2.99.910-0ubuntu1.6. I also tried
2.2.99.910-0ubuntu1.6. No change. I also tried to change the acceleration mode,
no change.

Attached find 
GPU crash dump saved to /sys/class/drm/card0/error
