Now I am trying to bisect from v4.1 to v4.4 to detect the commit breaks the things.

Beware that bisection there might be difficult since there were lots of rewrites due to drm atomic modesetting... Fingers crossed :) -- You are receiving this mail because: You are on the CC list for the bug.

OK, now I tried to backport the upstream commit 8581f1b5ee08.

The test kernel is being built in OBS home:tiwai:bnc1009674 repo. It takes some time (1 or 2 hours, usually) until the package is built and published. Please give it a try later. Once when it's confirmed to work, I'll merge the patch to SLE12-SP2 / openSUSE-42.2 branch.

Either the patch isn't enough or it's not the exact patch fixing the issue.

I don't know why, video adapter is the same: 8086:0f31, but the system doesn't have HDMI output (only D-SUB).
