Description daniele356 2018-05-05 14:43:07 UTC 
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):
4.16.5-300

How reproducible:
Suspend the system and wake It up.

Steps to Reproduce:
1. Suspend the current session
2. Wake It up

Actual results:
CPU frequency goes high.

Expected results:
CPU frequency changes slightly.

Additional info:
I own an Asus Laptop (K Series) with an Intel Core i7 (6th generation) as CPU.
Comment 1 daniele356 2018-05-05 14:45:39 UTC 
The GNOME Shell extension name is "CPU Power Manager" and not "CPU Frequency Manager".
Comment 2 daniele356 2018-05-11 16:54:55 UTC 
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.
Comment 3 daniele356 2018-05-21 16:52:03 UTC 
I've just upgraded the kernel to version 4.16.8-300.fc28.x86_64 and now the problem is solved!
