Comment 2 Chris Wilson 2019-10-27 14:41:12 UTC

The test relies on i915.reset being the default value: https://patchwork.freedesktop.org/series/68602/

Comment 3 Chris Wilson 2019-10-27 19:35:55 UTC

commit def00442d5b9cbe6ca18ead23d80e8501d3fd517 (HEAD, upstream/master)
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date:   Sat Oct 26 20:33:54 2019 +0100

    i915/gem_ctx_exec: Enable resets for basic-nohangcheck
    
    Wrap the test inside igt_allow_hang as we depend upon a fast reset to
    cancel the hostile context.
