[Sat Jun 29 10:24:11 2019] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.

Comment 1 Chris Wilson 2019-06-29 09:52:20 UTC
Please reproduce with a recent kernel, say 5.1, or even better with drm-tip [https://cgit.freedesktop.org/drm-tip] if you want to be in a position to test patches.

For what it's worth, I think we fixed this bug about 3 years ago.
