Public bug reported:
System information:
CPU: Intel Core i3-4005U 1.70GHz
Ubuntu release: Ubuntu 22.04 LTS (Jammy Jellyfish)
Laptop: Dell Inspiron 14 3458
Issue:
Ubuntu can't run full speed the CPU, only limit at 1.60GHz. All governors can't
run to 1.70GHz, but Windows 10 (Dualboot Ubuntu and Windows 10) can run up to
1.70GHz maximum. Temperature are not really hot, normal work at 50~69 celsius
degree but when heavy load only at 70~80 celsius degree. What I expected to
happen is Ubuntu still use full speed of CPU and not get any throttle or limit
but what happened instead is Ubuntu can't use full speed (like Intel CPU
throttle).
