Maybe the error messages could be improved to indicate that they aren't serious? Something along the lines of "Failed to retrieve minimum clocks, falling back to $foo."? >>> [ 51.611918] amdgpu: [powerplay] >>> failed to send message 282 ret is 254 > > These may be fixed by this patch if you are using an older pcie gen1/2 platform: > https://patchwork.freedesktop.org/patch/259364/ I've applied that patch on top of 4.19.4 but I'm still seeing: [ 17.407112] amdgpu: [powerplay] failed to send message 282 ret is 254 And as far as I know, I do have PCIe Gen3: [ 14.992861] [drm] PCIE gen 3 link speeds already enabled Cheers, Kai
