Maybe it would be a good idea for you to take the offer from https://bugs.freedesktop.org/show_bug.cgi?id=93352#c20 ("Please let us know if we can assist by providing people working on driver issues a copy of the title") - I'm sure this will speed up debugging a lot.
Not that this is the proper channel for this, but I replied to that offer here: http://lists.freedesktop.org/archives/mesa-dev/2015-December/103085.html
