Oh, the infamous. We have a report of these for pretty much all our our hw
platforms up to ivb (I think hsw is fine actually). Played around with
piles of things to no avail thus far. For 3.15 there's two patches from
Imre which might improve this mess (since in general if the pipe stops
running when we don't expect it to our code will hang all over the place
since we don't have a hangcheck for the display hardware):
2e82a7203182d0883d0f9450d40ad6e1c6578ad9 drm/i915: don't disable DP port after a failed link training
5d6a1116c6475404e6505b708320f9579ae19acd drm/i915: don't disable the DP port if the link is lost
Cheers, Daniel
