--- Comment #10 from Mauro Gaspari <ilvipero at gmx.com> ---
I am also affected by this bug. I filed a bug with openSUSE tumbleweed and bug
was closed earlier this year.
However, with latest mesa updates, the issue resurfaced, therefore I reopened
the bug. This is the link https://bugzilla.opensuse.org/show_bug.cgi?id=1090456

System Info:
OS: OpenSUSE tumbleweed x86_64 updated (2018 08 27)
Kernel: 4.18.0-1-default
Desktop Environment: KDE Plasma (x11)
OpenGL version string: 3.1 Mesa 18.1.6
GPU: AMD Radeon RX Vega 64 8GB 

Relevant log lines I found during freeze:

2018-08-09T23:16:53.103775+08:00 MGDT-Tumbleweed kernel: [ 6305.852703]
[drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx timeout, last signaled

2018-08-09T23:16:53.103795+08:00 MGDT-Tumbleweed kernel: [ 6305.852704] [drm]
No hardware hang detected. Did some blocks stall?

as a side note, the freeze does not happen on my Kubuntu system. Same hardware,
same games.
