Bug Description
sudo cpupower frequency-info
analyzing CPU 0:
driver: acpi-cpufreq
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 10.0 us.
hardware limits: 800 MHz - 2.80 GHz
available frequency steps: 2.80 GHz, 2.80 GHz, 2.70 GHz, 2.60 GHz, 2.40 GHz, 2.30 GHz, 2.00 GHz, 1.90 GHz, 1.80 GHz, 1.70 GHz, 1.50 GHz, 1.40 GHz, 1.20 GHz, 1.10 GHz, 900 MHz, 800 MHz
available cpufreq governors: conservative, ondemand, userspace, powersave, performance
current policy: frequency should be within 800 MHz and 2.80 GHz.
current CPU frequency is 1.40 GHz (asserted by call to hardware).
cpufreq stats: 2.80 GHz:3.03%, 2.80 GHz:0.01%, 2.70 GHz:0.27%, 2.60 GHz:0.68%, 2.40 GHz:0.70%, 2.30 GHz:1.52%, 2.00 GHz:2.20%, 1.90 GHz:1.36%, 1.80 GHz:1.80%, 1.70 GHz:3.38%, 1.50 GHz:3.78%, 1.40 GHz:5.64%, 1.20 GHz:7.07%, 1.10 GHz:13.71%, 900 MHz:28.54%, 800 MHz:26.32% (2921841)
