Public bug reported: [Impact] AMD Prairie Falcon is the AME Embedded variant of Stoney. 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] [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. ** Affects: linux (Ubuntu) Importance: Undecided Status: Invalid ** Affects: linux (Ubuntu Bionic) Importance: Undecided Assignee: AceLan Kao (acelankao) Status: In Progress ** Also affects: linux (Ubuntu Bionic) Importance: Undecided Status: New ** Changed in: linux (Ubuntu Bionic) Status: New => In Progress ** Changed in: linux (Ubuntu Bionic) Assignee: (unassigned) => AceLan Kao (acelankao) ** Changed in: linux (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1850572 Title: AMD Prairie Falcon platform failed to boot up Status in linux package in Ubuntu: Invalid Status in linux source package in Bionic: In Progress Bug description: [Impact] AMD Prairie Falcon is the AME Embedded variant of Stoney.
