Besides this other issue:

[   81.869168] [drm:intel_check_pch_fifo_underruns [i915]] *ERROR* pch fifo underrun on pch transcoder A
It seems that the warn

haven't appeared again on SNB.

According to Maarten, this issue happens only when GPU resets at the same time as atomic update. Lowering the priority.
Comment 14 Martin Peres 2018-11-01 15:57:57 UTC
Used to be seen multiple times per week, now nothing since CI_DRM_4456_full (3 months, 3 weeks / 2050 runs ago). Closing!
