Bug Description

Hi ! I didn't manage to find another software causing the crash. In my case, it's Velocidrone. I contacted the developpers but they don't know what happens to my system in that case.

Everytime I execute the game, I get this in dmesg (like 90%, so you can ask me to reproduce the crash while running some debugging tool if you ask me | I don't know why sometimes it doesn't). That causes my PC Wifi to crash, as you can see.

> Network: Device-1: Intel Wireless-AC 9560 [Jefferson Peak] driver: iwlwifi v: kernel

I also attached the full `journalctl` from today.

Hi. I come with some news. I found a workaround that is not the best, but works.

I have set up my AP to separate SSID for 2.4Ghz and 5Ghz.

I do not experience and trouble in 5Ghz , except when running said game "Velocidrone".

On the other hand, I experiment unstable 2,4Ghz wifi link (connection to AP (MAC:ID) lost) with my wireless mouse (with usb flash) , undoubtedly because of interference, no matter the channel.

So I manually choose which band I want wether I want to play simulator, disconnecting the mouse, or simply surfing.

If course it'd be better if I everything was working without I to be worried about it.

Good day to you

Hello. I didn't see if there was an update, but I didn't experienced any iwlwifi crash for days. I couldnt reproduce the bug for 4 days in a row.

I don't recall doing anything that could affect this in anyway.
