Comment 6 Chris Wilson 2017-11-28 14:53:56 UTC
commit 448aa9117cfa6591c4e18cb32a0329a66b9cd3b7
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date:   Tue Nov 28 11:01:47 2017 +0000

    drm/i915: Enable hotplug polling after registering the outputs
    
    Previously we would enable hotplug polling on the outputs immediately
    upon construction. This would allow a very early hotplug event to
    trigger before we had finishing setting up the driver to handle it.
    Instead, move the output polling to the last step of registration, after
    we have set up all handlers, including the fbdev configuration.
    
    v2: Symmetrically turnoff the hotplug helper in unregister after the
    fbdev is first synchronised then finalized. This stops a late hotplug
    event being processed after the interrupts are disabled.

Last time the issue was seen on CI_DRM_3400. The fix was integrated on CI_DRM_3401. There has been 17 clean CI_DRM and IGT runs, I say the fix is legit and colse the bug.
