Public bug reported:
I would really like to find out why my cpu's keep reverting back to a cpu powersave mode after I get a kernel update then reboot. I cleaned my laptops vent but this seems to happen whenever a new kernel is updated and installed. https://askubuntu.com/questions/1366090/ubuntu-20-04-3-lts-significant-
