For whatever reason the test failed due to an inexplicable delay, hitting cleanup code never before executed and which doesn't exist!
Ignoring the root cause of the erroneous delay, and merely focusing on the secondary explosion: commit d315d4faf82092df6fe82f456fd26dc8b247b627 (HEAD -> drm-intel-next-queued, drm-intel/for-linux-next, drm-intel/drm-intel-next-queued) Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Tue Mar 19 21:42:33 2019 +0000 drm/i915/selftests: Provide stub reset functions If a test fails, we quite often mark the device as wedged. Provide the stub functions so that we can wedge the mock device, and avoid exploding on test failures.

It happened twice in 4 runs, and now nothing for 180.
