Kconfig should probably not have allowed the FB_SIMPLE=yР”ВRM_SIMPLEDRM=m configuration for a 'bool' driver before That said, I see two additional bugs that have made your life harder: If you just turn off CONFIG_DRM_SIMPLEDRM, you should get back With my patch, the broken configuration is no longer possible,Р”Р„nd you have to choose between one of the two drivers beingР”В«uilt-in, or both as loadable modules, using a localР”В¬onfiguration to decide which one to load on a given machine.

Here's the difference between 5.14.10 and 5.14.12 configs: Whenever I boot 5.14.11/5.14.12 the screen is completely black.
