commit 37ef01ab upstream. We stopped handling them in commit aaecdf61 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Tue Nov 4 15:52:22 2014 +0100 drm/i915: Stop gathering error states for CS error interrupts but just clearing is apparently not enough: A sufficiently dead gpu left behind by firmware (*cough* coreboot *cough*) can keep the gpu in an endless loop of such interrupts, eventually leading to the nmi firing. And definitely to what looks like a machine hang. Since we don't even enable these interrupts on gen5+ let's do the same on earlier platforms.
