--- Comment #4 from Danilo Pianini <danilo.pianini at gmail.com> ---
I was able to reproduce the problem and ssh into the system. I attached the log
already.

Steps to reproduce:
1) Open Google Chrome
2) Visit www.youtube.com
3) Open a random video, watch the first 10-20 seconds
4) If the problem does not happen, goto 3 (it normally takes 2-5 attempts)


relevant dmesg:
[40741.804076] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[40741.804079] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[40741.804081] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[40741.804084] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
