With any luck, this should be covered by: commit 9a3b19a16dc28ab717cf1663d09ffee0715b735a Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Wed Feb 13 23:20:47 2019 +0000 drm/i915: Only try to park engines after a failed reset Currently we try to stop the engine by programming the ring registers to be disabled before we perform the reset. Sometimes, we see the context image also have invalid ring registers, which one presumes may be actually caused by us doing so. Lets risk not doing programming the ring to zero on the first attempt to avoid preserving that corruption into the context image, leaving the w/a in place for subsequent reset attempts.
