Can you test one additional kernel? It is the current Xenial kernel with commit 237ed86c also reverted. If this one is good, then commit 7a5c500 (drm/i915: Fix hpd live status bits for g4x). Needs some more work.
The latest test kernel is in the usual location:
http://kernel.ubuntu.com/~jsalisbury/lp1543683/
