Kind of expected... We depend upon the hw validation reporting an error for bad registers -- the point of the test is to make sure that the hw does report such errors if we make the mistake at runtime.
Rising priority since it got our test cycles stuck for hours until we manually power platforms off.
Fwiw, this test is now disabled (by default): commit 69ea47a5a98b198c9d36fe157a3986748a9e2554 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Wed Oct 25 16:32:07 2017 +0100 drm/i915/selftests: Hide dangerous tests Some tests are designed to exercise the limits of the HW and may trigger unintended side-effects making the machine unusable. This should not be executed by default, but are still useful for early platform validation.
