I'm using a Rx 560 on kernel 4.16 and my clock rate is stuck on 1230MHz permanently. I'm also using a single 2560x1440x144 monitor This is directly related to DC. If I run with amdgpu.dc=0 the issue disappears. If I run with amdgpu.dc=1 it shows up. I can't say if it also happened on 4.15 or earlier. I did notice that dmesg shows about a dozen powerplay errors: [ 94.582083] amdgpu: [powerplay] failed to send message 146 ret is 255 [ 94.582091] amdgpu: [powerplay] failed to send pre message 147 ret is 255 [ 95.895976] amdgpu: [powerplay] failed to send message 145 ret is 255</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
