Flipping to xserver-xorg-video-intel since there are loads of i915 errors in the current-dmesg logs.

Karol: Tell us a bit more about your setup; what displays do you have connected, via what interface?
From the logs I think you have one on an HDMI output, and something else (lower res?) on a Display Port?

The root cause is the GPU hang presumably caused by mesa. The subsequent pin leak should be fixed by

    drm/i915: Flush outstanding unpin tasks before pageflipping

You're correct, PC is connected to a LCD TV through HDMI cable.

What is bizarre is that it used to work just fine since Feb of March when I installed it and it started to crash rather frequently last week.
