I've been running mostly on the power saving CPU scheduler because on any others, k10temp reports that my CPU idles around 1.44V - Nice to know that it was (probably) just a display bug.


This is just the hwmon reporting part, it does not seem related at all to voltage scaling as the headline makes it sound.
