Ah well that makes sense as to why the power usage is still low. Good to know
that powerd really isn't really needed here for this Ryzen setup. I can live
happy knowing it's not just chewing power away like a dog eating styrofoam
blocks, but I'm happy to perform any tests if need be and report back.

Bit concerning that setting the frequency causes a reset like that though, it
makes things super hard to debug. I did try with microcode updates enabled as
well after updating the BIOS (and made sure microcode_amd_fam17h.bin exists
too), but it doesn't report that it updated anything and the problem persists.
There isn't any other concerning errors in the logs at all to indicate a
problem.
