["Jonas G. Drange" <1354046@xxxxxxxxxxxxxxxxxx>]

I've near searched to the end of Google to find a solution. One of my
observations is that the symptoms of other bugs never matches the
symptoms of this bug. On my laptop, everything seems to be OK—that is,
until I run some thing requiring 3D. Then my machine grinds to a halt.
No logs, no nothing. 100% on all four cores.

So, I'm thinking, what is _something_ is misbehaving, but the system
believes everything to be OK? The answer to that, it seems, is cpu
frequency scaling.

My CPU cores are scaled using the 'powersave' governance. Using Half
Life 2 as a benchmark (this game ran well on trusty, but currently is
not playable after 1.5 minutes), I looked at what happened to cpu
frequencies while playing the game. At first, all four cores jumped to
3GHz [1]. Then, surprisingly, they were lowered to ~130 MHz [2].

Uh.

So, setting my cpu frequency scaling governance to 'performance' partly
fixes this issue.

Bug description:
  Description:
  3D games, video (especially flash) makes computer unresponsive. The problem has been present since upgrade to Utopic, but have recently become worse, maybe  because of error message

  [drm:intel_dp_start_link_train] *ERROR* too many full retries, give up

  which appears in all terminals.

  How to reproduce:
  Start a 1080p video. e.g. Note that the video is not run from an encrypted folder.
  Or watch a video on youtube.
  Reproducable for new users as well, so not related to /home/$USER

  What happens:
  Usage on all four CPUs on my DELL XPS 13 DEVELOPER EDITION will be between 30% and 100%.

  What I expected:
  Expected same 3D performance as on Thrusty.
