--- Comment #113 from Jason Playne <ja...@jasonplayne.com> ---
As others have noted, with powerplay doing its thing we get system freezes.
Just had a successful 6+ hour gaming session on a kernel 5.3.2-050302-generic
with the following being done:
* Forcing high perf state
* Undervolt/Overclock
* Higher fan curve (https://github.com/grmat/amdgpu-fancontrol)
I know that I have been messing with all sorts here, but I think it suggests
that PowerPlay may be at fault here when my system *does* crash (which is all
the time without the force high perf state)
All details below:
# Forcing High Perf
echo high | sudo tee
/sys/class/drm/card0/device/power_dpm_force_performance_level
# Undervolt / Overclock
I also have done some messing around with voltages/clocks
$ cat /sys/class/drm/card0/device/pp_od_clk_voltage
