/sys/class/drm/card0/error (requested by syslog message)

I'm using debian jessie with uptodate packages.
It is the second time that IGP is crashing during the wallpaper.
Wallpaper was active long time before crash.
I hope that the attached dump will be useful.

   * What led up to the situation?
maybe the wallpaper, but I don't really believe it
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
nothing
   * What outcome did you expect instead?
I'm expecting no crash

I'm using intel core i5-7600 with 4k at 60Hz desktop.
