--- Comment #4 from Armin K krejzi@email.com --- Well, the same config worked in pre 4.9-rc1 drm-next. The module and kernel were compiled together. However, this config is, and always has been, building amdgpu/ttm as a module, and the rest of the drivers (very minimal set, tied to this machine only) as built-in.
