Created attachment 130353 [details] Screen shot Bisected back to: 2d38d25554b739b50eec254205f769580751fb02 is the first bad commit commit 2d38d25554b739b50eec254205f769580751fb02 Author: David Panariti <David.Panariti@amd.com> Date: Mon Mar 13 13:33:18 2017 -0400 drm/amdgpu: Switch baremetal to use KIQ for compute ring management. KIQ is the Kernel Interface Queue for managing the MEC. Rather than setting up rings via direct MMIO of ring registers, the rings are configured via special packets sent to the KIQ. The allows the MEC to better manage shared resources and certain power events.
