Hmm, but then why will the machine not restart unless I use sysrq keys? I would
think a userspace issue wouldn't cause hung kernel tasks like that.

I'm also curious regarding why this program is causing the GPU to reset to
begin with, I have not seen others reporting issues on other platforms with
this program.

Is this ring gfx timeout purely a problem with userspace?

e.g.
[drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx timeout, signaled
seq=32203, emitted seq=32205
