Description

Running a polaris Pro Duo on Ubuntu 18.04, Kernel from ROCm branch 4.17.0-rc2-180424-fkxamd and everything works great.

In testing latest drm-next-4.19-wip kernel, I get the following errors on boot, and have no working opencl (ie clinfo hangs indefinitely)


[ 58.913281] [drm:amdgpu_job_timedout [amdgpu]] ERROR ring sdma0 timeout, signaled seq=573, emitted seq=574
