iwlwifi AP spams dmesg

I have my wifi card in my laptop set up as an access point (using this script: https://github.com/oblique/create_ap) and it keeps printing messages in dmesg. I have already stopped them in the ttys by adding `dmesg -D` to /etc/rc.local, but sometimes I have to look for something in dmesg and it's filled with these messages:

[ 5871.942895] iwlwifi 0000:02:00.0: beacon intervals don't match (0, 100)
[ 5872.439978] iwlwifi 0000:02:00.0: beacon intervals don't match (0, 100)
[ 5934.997919] iwlwifi 0000:02:00.0: beacon intervals don't match (0, 100)
[ 5935.547197] iwlwifi 0000:02:00.0: beacon intervals don't match (0, 100)

This happens as long as the AP is running. Is there any way to stop this? It is not impacting my AP performance at all AFAIK.

Re: iwlwifi AP spams dmesg

Please do not bump.  These are active forums -- if no one responds it is because we don't have an answer.

You elected to use a script you found on the Internet.  We have no clue what that script does.  I see they provide instructions that relate to the AUR?  Did you install it according to that suggestion?
Have you asked the author of the script on github?   If you used the AUR, have you made a comment on the AUR page for the script?

Is there a reason you did not use the wiki article?

Lastly, when the forums give you crickets, try providing more information.  What hardware are you running?   You might tell us what you learned from the linked articles after you fed the search term "iwlwifi beacon intervals don't match" to your favorite search engine.

Re: iwlwifi AP spams dmesg

Yes, I have installed the script using the AUR. The script creates a virtual interface and starts a accesspoint via hostapd. I have read the wiki article and did not seem to find useful information. I don't think the message is because of the script. There is this issue  (https://github.com/oblique/create_ap/issues/53), but the problem (packet loss) doesn't seem to be related to the error message.
The output of lspci is:

It's a intel WiFi adapter built in to the laptop.
