Bug Description

Not sure where this goes, but no cpufreq driver is available in 19.10 or 20.04 on AMD CPUs. I'm not sure why this is happening, but no cpufreq driver gets loaded.

Did it work on Disco i.e. Linux kernel v5.0?

It did definitely work in 19.04, but cannot find a CPU governor on 19.10 or Focal.

Tested on a system with A12-9800E and it doesn't seem to have this issue.

Can you please perform a kernel bisection?

I did a kernel bisection back to 5.0 (in disco) and the problem still persisted. It could be a firmware problem with my machine, but I'm uncertain.

Found out the problem. It was indeed a firmware update with my BIOS which disabled a power-on-demand item in the ACPI. Closing this.
