Not always. On the latest attempt to understand the bug, i run mplayer for 4-5
hours. And then my screen was black, responded to nothing, I hit SysRq +
REISUB, but it didn't help. Only removing the power cable saved me. 

This single message remained:

[drm] stuck on render ring
[drm] GPU crash dump saved to /sys/class/drm/card0/error
[drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including
userspace.
[drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI ->
DRM/Intel
[drm] drm/i915 developers can then reassign to the right component if it's not
a kernel issue.
[drm] The gpu crash dump is required to analyze gpu hangs, so please always
attach it.
[drm:i915_reset] *ERROR* Failed to reset chip: -19
