For me the hang happens always when running the 'mogrify' command line tool from imagemagick. It is compiled to use *OpenCL* when available. I have opencl installed, from Mesa clover. Using radeon RX560. When I disallowed access to /dev/dri/card* for the user running this program, then hangs stopped. I think the problems started when I upgraded the system LLVM from 5.0.1 to 6.0 and rebuilt Mesa (I'm using git checkouts). Before that, mogrify with OpenCL didn't hang the GPU and was running fine. The symptoms after the hang are similar to what <a class="bz_bug_link bz_status_NEW " title="NEW - Amdgpu randomly hangs and only ssh works. Mouse cursor moves sometimes but does nothing.
