On my BDW NUCi5 the:

kms_frontbuffer_tracking --run-subtest fbc-1p-primscrn-spr-indfb-fullscreen

fails on the second and every following consecutive runs

igt at 9fe5a9a3de
drm-tip 4.14.0-rc8+

While running all kms tests with:
drm-tip at d2ec28c538
igt at cdfe992134b, this issue didn't happen ~2 weeks ago. However, I reproduced
the issue with same configuration today.
