I reported this in bug https://bugs.freedesktop.org/show_bug.cgi?id=91495 with the stipulation that sometimes the error [drm:i915_hangcheck_elapsed [i915]] *ERROR* Hangcheck timer elapsed... render ring idle would show in my syslog. That seems to not be the case anymore as it hasn't shown up since 28 July 2015. I've also reported the latest issue to Ubuntu Launchpad https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1497627 which states simply Periodically video will freeze for no reason at all and no specific time between freezes. Christopher M. Penalver who I assume is a member of the Ubuntu kernel bug team has had me try several things as noted in my Ubuntu bug report above. The latest was today when he had me install and attempt to boot into the latest upstream kernels at http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D which I did this morning. Of those listed starting at the top of the list this is what happened when trying to boot into them v4.3-rc3-unstable - Boot process would begin but would not complete v4.3-rc2-unstable - Same as above v4.3-rc1-unstable - Same as above v4.2.3-unstable - Boot process completed however I noticed when switching desktop windows a flickering of the video The video flickering is slight most times but it's there.
