Ubuntu 21.10 on Dell XPS 13 9310 WiFi Killer AX500s DBS stopped working in kernel 5.13.0-21-generic
This works again with the now released kernel 5.13.0-22.
sudo apt update
sudo apt upgrade
sudo reboot
and if you never want to see this again:
sudo apt purge linux-headers-5.13.0-21 linux-headers-5.13.0-21-generic linux-image-5.13.0-21-generic linux-modules-5.13.0-21-generic linux-modules-extra-5.13.0-21-generic
