errors logged by the kernel

Occasionally when using the Chromium browser, X will freeze. This is
accompanied by various errors in the kernel log (see attachment). I can
reliably reproduce this by opening the following websites in Chromium:

  * https://www.youtube.com/
  * http://www.ardmediathek.de/tv
  *
https://developer.mozilla.org/en-US/docs/Web/API/WebGL_API/Tutorial/Lighting_in_WebGL

This is with X server 1.19.6 and xf86-video-nouveau 1.0.15.

I originally saw this with Linux v4.16 and then reverted back to v4.14.35 LTS
which didn't seem to exhibit the same problems at first. Also, with v4.16
the
freezes seem to be more extensive, often requiring a reboot. With v4.14.35 the
freezes are temporary and often even non-existent despite the errors logged by
the kernel.

--- Comment #1 from Darek <dz1125.bug.tracker at gmail.com> ---
This [1] patch prevents random xserver freezes
tested:
GPU GTX 550Ti
mesa 18.1.0rc2
xorg-server 1.19.99.905
xf86-video-nouveau-git 1.0.15.r5.gac8f7b9
DRI3 enabled

I noted the same behavior with:
mesa 18.0.1-1
xorg-server 1.19.6+13+gd0d1a694f-2
xf86-video-nouveau-git 1.0.15.r5.gac8f7b9
DRI3 enabled

I'm not sure if it is related, but it's worth mentioning
