I doubt it as amdgpu is not even built (# CONFIG_DRM_AMDGPU is not set, see
attached .config).

The card in question is a Radeon HD 6670 using the radeon drm module. Sorry I
forgot to mention that!

Have not seen this since quite a few stable kernel releases on the same
hardware. I think it's save to close here.
