If it happens during media playback, a suspected culprit is the video driver,
of course.  What video driver are you using?

If it's i915, there has been a fix for i915 freeze recently.  Did you ever test
with a newer upstream kernel (3.18 / 3.19)?  Also, what about the newer
openSUSE-13.2 kernel in OBS Kernel:openSUSE-13.2 repo?
