Bug ID: 105880 Summary: [dc][kabini] Cannot find any crtc or sizes Product: DRI Version: XOrg git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: chithanh@gentoo.org
Created attachment 138570 --> https://bugs.freedesktop.org/attachment.cgi?id=138570&action=edit dmesg with cik_support=1 dc=1
When using kernel 4.16.0 and amdgpu with cik_support=1 dc=1 on Kabini (A4-1200) the screen will become blank once the module is loaded.
dmesg has the following error: [drm] Cannot find any crtc or sizes
With radeon or amdgpu.dc=0 the screen lights up, but I cannot use amdgpu for daily work due to bug 101926.
