PWM frequency failed

Hey, guys!

After the last week updates I noticed some messages in red during boot. I am not saying the updates caused them and actually everything works fine but if there is a way to clear those messages I will feel better.
Here is the output

 systemctl --failed

  UNIT                                                     LOAD   ACTIVE SUB    DESCRIPTION
● pwmfrequency@0x05000500.service loaded failed failed LED PWM frequency
● pwmfrequency@0x07a107a1.service loaded failed failed LED PWM frequency
● pwmfrequency@0x43d043d.service loaded failed failed LED PWM frequency
● pwmfrequency@0x7a107a1.service loaded failed failed LED PWM frequency

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

4 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.

intel_reg_write 0xC8254 0x7a107a1
-bash: intel_reg_write: command not found

I have the pwmfrequency@.service file in /etc/systemd/system following the instructions here https://wiki.archlinux.org/index.php/ba … 15_only.29 and here http://devbraindom.blogspot.com/2013/03 … intel.html and the current frequency is set to 500 Hz.

Any help is highly appreciated!
Thank you!
