--- Comment #14 from e88z4 <felix.adrianto at gmail.com> ---
I tried to reproduce this bug again with latest mesa master (659aa3dd651). My
kernel is 5.1.3 and yuzu-canary #2318. The behaviour of the softlock is
slightly changed. Yuzu didn't crash anymore but rendering was super slow. I was
able to kill the application without using SSH. The following error was
produced from dmesg.

[ 5179.131132] [drm:amdgpu_dm_atomic_commit_tail [amdgpu]] *ERROR* Waiting for
fences timed out.
[ 5183.739102] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx timeout, but
