Does this work on the stable kmod? We are in the process of updating -next to 4.15.
(In reply to Johannes M Dieterich from comment #2)
I can't easily install STABLE on this machine.
No, I was referring to graphics/drm-stable-kmod. Does it work with that?
As I said, it's very unlikely that any major fixes are going to happen in graphics/drm-next-kmod prior to the 4.15 import.
Does this work now?
