Hello,
I was watching a DVD in VLC player and suddenly the movie stopped. Following
lines appeared in dmesg log:

[54302.190194] [drm] stuck on bsd ring
[54302.190199] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[54302.190200] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[54302.190201] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[54302.190202] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[54302.190203] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
