kernel .config (kernel 5.16-rc7, Talos II)
does appending amdgpu.runpm=0 on the kernel command line help? (In reply to Alex Deucher from comment #2) > does appending amdgpu.runpm=0 on the kernel command line help? 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. |
