The following two tests failed on the machine fi-gdg-551:

 - igt@gem_mmap_gtt@basic-small-copy-xy: http://intel-gfx-ci.01.org/CI/CI_DRM_2614/fi-gdg-551/igt@gem_mmap_gtt@basic-small-copy-xy.html

Closing since it has not been seen since May 24th, just like bug 100998.
Comment 2 Chris Wilson 2017-06-15 12:00:36 UTC 
Hmm, that suggests it was related to

    drm/i915/g33: Improve reset reliability
    
    We improved the reset reliablity on gen4 with
    stopping all engines before commencing reset, in
    commit 2c80353f3cd0 ("drm/i915/g4x: Improve gpu reset reliability")
    
    Evidence indicates that this same trick works with g33.

Odd.
