Comment 4 Chris Wilson 2017-02-01 09:39:17 UTC 
4.4 is very old for skl; recommendation is to update to 4.9 to have the known set of workarounds. Similarly make sure your mesa is uptodate.
Comment 5 Peter Davies 2017-02-01 10:17:56 UTC 
Have updated Mesa from 11.2.2 -> 13.0.3
Kernel (I assume that is what skl is) is harder to do so will see if that helps.

Issue has been resolved by the Mesa upgrade.
