Varies, I'm not punishing the box atm, so it might be 3300, 1300, 1000, ... freq_levels is (under a -p4 kernel) dev.cpu.0.freq_levels: 4001/88000 4000/88000 3800/81704 3500/72258 3300/66530 3100/60999 2900/55687 2600/48456 2400/43627 2200/39003 1900/32072 1700/27930 1500/23963 1300/20178 1000/15137 800/11779 for a p7 freq_levels / freq I'd need to reinstall a known (for me) bad upgrade again, and reboot, brr Waiting for further suggestions of data to collect and will do all in one go, when I'm done with work.
