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 Brieuc -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1918723 Title: iwlwifi crash when running a software AC Status in linux-firmware package in Ubuntu: New 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. --- ``` [ 4232.602167] iwlwifi 0000:00:14.3: Queue 11 is active on fifo 1 and stuck for 10000 ms.
