The revert of that patch is already on it's way to Linus. |
I have a laptop with an AMD Rembrandt APU (6800U). The display has a native resolution of 2880x1800, however, via `~/.config/monitors.xml`, I set it 1920x1200. After the upgrade to the kernel v6.3.9, the resolution 1920x1200 is not allowed anymore, and on login, I see a brief popup with an error. After bisection, i've isolated the culprit to commit `edcfed8671` ("drm/amd/display: edp do not add non-edid timings").
