Description of problem:
I noticed that my CPU frequency goes high after waking up my system from suspension even if no process running. It oblige me to force system shutdown and reboot.
P.S. gnome-system-monitor doesn't show me these results but the "CPU Frequency Manager"(https://extensions.gnome.org/extension/945/cpu-power-manager/) GNOME Shell Extension does.
Version-Release number of selected component (if applicable):
Suspend the system and wake It up.
Steps to Reproduce:
1. Suspend the current session
2. Wake It up
CPU frequency goes high.
CPU frequency changes slightly.
I own an Asus Laptop (K Series) with an Intel Core i7 (6th generation) as CPU.
The GNOME Shell extension name is "CPU Power Manager" and not "CPU Frequency Manager".
This situation is becoming really annoying, I can't suspend the system because I can't shutdown It after I resumed the session; so I'm obliged to lock the session instead of suspend It but this consumes more battery and this is even more annoying.
I've just upgraded the kernel to version 4.16.8-300.fc28.x86_64 and now the problem is solved!
