I have not dig into this code, but only tried if reverting helps. It does. The problem is gone without this commit. I have reported this solution also on the two bug-reports i made: Booting problem: https://bugs.freedesktop.org/show_bug.cgi?id=109398 xset dpms force off: https://bugs.freedesktop.org/show_bug.cgi?id=109399 Both bugs are solved by reverting this commit 49218c8 introduced with the release of kernel 4.19.3. Now hoping that someone will revert this commit or change the code so it works properly.... @David. Thanks for pointing me to the development kernel from drm-tip! -- You are receiving this mail because: You are on the CC list for the bug.
