Description C. Kimna 2016-02-25 23:59:14 UTC 
Following message during shutdown - about 50 lines with:
drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!

Tested with various distributions on two Intel NUC5i7 devices (OpenSuSE 13.2, 42.1 with KDE4/KDE5 and Ubuntu MATE 15.10 Live with Compiz). All the same on all tests.

kernel 4.1.12 works on desktop (some juddering on games)
kernel >4.2 doesn't work without erros
