Hi Chris, I tried now first installing the powertop rpm and than running it, on a Fedora 25 x86_64 platform, and I get exactly the same results: ... ls /var/cache/power* -l total 0 -rw-r--r--. 1 root root 0 Jan 11 19:30 saved_parameters.powertop -rw-r--r--. 1 root root 0 Jan 11 19:30 saved_results.powertop desku:~$powertop -c modprobe cpufreq_stats failedLoaded 0 prior measurements RAPL device for cpu 0 RAPL device for cpu 0... I don't know what does this message mean, whether it indicates some anomaly or not.
