Looks like the amdgpu driver has never fully initialized GDS support for SI family GPUs, and this now triggers the DRM_MM_BUG_ON which was added to drm_mm_init in 4.11. AMD folks, should this be addressed by fleshing out SI GDS support, or by completely disabling GDS initialization for SI? -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Mesa and X developer
