+Subject: [PATCH] drm/i915: Dont enable CS_PARSER_ERROR interrupts at all
+
+We stopped handling them in
+
+commit aaecdf611a05cac26a94713bad25297e60225c29

+
+ 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.
