Description:
Using the linux kernel 4.5.x on arch linux updated is causing high use of power, 78% more than linux-lts version 4.4.9.
Observing the abrupt reduce of battery duration, I checked it using powertop utility.
I do not see a specific process with high use of cpu.
To use X11 to wayland do not change anything.


Additional info:
* package version(s)
* config and/or log files etc.

Using Samsung Ative Book 6 open powertop utility and compare linux 4.5.x with linux-lts.

Steps to reproduce:
   dmesg.txt (60 KiB)
   journalctl.txt (439.1 KiB)
   lspci.txt (1.7 KiB)
   lsusb.txt (0.6 KiB)
   packages.txt (31.3 KiB)
This task depends upon
