  "message": "drm/i915: kicking rings stuck on semaphores considered harmful\n\nIf our semaphore logic gets confused and we have a ring stuck waiting\nfor one, there\u0027s a decent chance it\u0027ll just execute garbage when being\nkicked. Also, kicking the ring obscures the place where the error\nfirst occured, making error_state decoding much harder.\n\nSo drop this an let gpu reset handle this mess in a clean fashion.\n\nIn contrast, kicking rings stuck on MI_WAIT is rather harmless, at\nworst there\u0027ll be a bit of screen-flickering. There\u0027s also old\nbroken userspace out there which needs this as a  work-around.\n\nSigned-off-by: Daniel Vetter \u003cdaniel.vetter@ffwll.ch\u003e\nReviewed-by: Chris Wilson \u003cchris@hchris-wilson.co.uk\u003e\nReviewed-by: Ben Widawsky \u003cben@bwidawsk.net\u003e\nSigned-off-by: Keith Packard \u003ckeithp@keithp.com\u003e\n",
