Comment 1 Martin Peres 2018-07-18 08:24:46 UTC
The vast majority of the failures are on the fi-bdw-gvtdvm machine, so I will consider it a gvt-d issue.

Comment 3 Martin Peres 2019-04-11 06:42:42 UTC
This bug is actually a duplicate of many other bugs:

And after that, only one failure was caught, 9 months ago:

https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_4454/shard-hsw5/igt@kms_frontbuffer_tracking@fbc-2p-primscrn-pri-shrfb-draw-mmap-cpu.html

Subtest fbc-2p-primscrn-pri-shrfb-draw-mmap-cpu failed.

Thus, we can close this bug altogether! Wasn't painful at all :D
