Similar according to Imre on
> Series: drm/i915: Prevent the system suspend complete optimization
> URL   : https://patchwork.freedesktop.org/series/22863/
> State : failure

https://intel-gfx-ci.01.org/CI/Patchwork_4476/fi-bsw-n3050/igt@kms_sink_crc_basic.html

Looks unrelated, but this is more like
https://bugs.freedesktop.org/show_bug.cgi?id=100417
as opposed the cited fdo bug.
