--- Comment #120 from blppt at yahoo.com ---
I dont have anything to attach here, but same issue here, ubuntu 19.04, kernel
5.4-rc3, vega64 W/C, Mesa 19.3.0 -- it only seems to occur with DXVK and not
D9VK for some reason.

Example: GW2 (DX9 game) will work perfectly under heavy load in WvW with
massive zergs for hours with no crash, but FFXIV (DX11) will always lock the
entire system up after a time.

That being said, when you force the top clock using

echo manual > /sys/class/drm/card0/device/power_dpm_force_performance_level


echo 7 > /sys/class/drm/card0/device/pp_dpm_sclk

FFXIV no longer locks the system at all. It does eat up a good deal more watts
according to my UPS meter though, so resetting to auto is necessary IMHO.

So, it sounds like you guys are on the right track with the whole "power
management" thing being the culprit. Just wanted to add my experience to this.

(and yes, echoing the guy above, the exact same system is stable in windows 10,
so its not a hardware issue).
