Same issue here with Vega 64. From watching
/sys/kernel/debug/dri/0/amdgpu_pm_info my conclusion is that basically driver
gets max voltage applied even though tables in
/sys/class/drm/card0/device/pp_od_clk_voltage suggest otherwise. I did test
with Windows 10 and applied same pp_od_clk_voltage - no issues. For testing I
applied 1.2V for all states and had same result with amdgpu. Tested on 5.0.3
and 5.0.4 ubuntu mainline kernel.
