Linux 4.14.0 libdrm 2.4.89 mesa 17.3.1 on Debian

01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Baffin [Radeon RX 460] [1002:67ef] (rev cf)

After lockup I see this message:

but similar message earlier did not cause lockup

Earlier versions of kernel+mesa would occasionally lock up displaying garbage randomly at any time. I have not seen that for a while but the card still occasionally locks up when running a 3D application. After lock up the card keeps showing static screen of something the application rendered and movable cursor. It seems to happen most often when there is some setup in progress like loading a new scene.
