I tried this and that without success. Honestly the intel hardware seems to be such cheep junk, that I feel sorry paying for that.
Given Haswell is >2 years old, it ought to work for everybody using it with any distro as new as Jessie...
I know I wanted to try the latest intel driver version, but never got the time and courage.
example

[ 5742.227815] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
Obviously some kind of incompatibility between your hardware and the software exists. Before giving up, or as suggested, filing a freedesktop DRI/DRM bug, I suggest bringing your problem to http://lists.freedesktop.org/mailman/listinfo/intel-gfx to see if it's a known problem or one already solved in software you've not tried. Maybe ULT is the problem rather than a more general Intel problem. Another possibility is what you have is a warranty problem.
