It fails to boot up without disable its CGCG feature. Set 'amdgpu.cg_mask=0xfffffffb' kernel parameter to disable CGCG [Fix] Suggestion from AMD that we have to cherry pick this commit which is included in v4.16 fb4bbba27753 drm/amdgpu: re-enable CGCG on CZ and disable on ST [Test] Verified on AMD Prairie Falcon platform, system boots up normally. [Regression Potential] Low, this commit has been included for more than one and a half year in the upstream, should be pretty safe to include it.
