Same problem here on Ubuntu w/Dell 9310 and AX500.

Reverting to 5.13.0-19 resolved the issue. First reboot didn't fix the issue, but a full power cycle did.

I used a USB wifi dongle to install. Without that, you might need to grab the relevant dpkgs and put on a USB stick to update.

sudo apt install linux-headers-5.13.0-19 linux-headers-5.13.0-19-generic linux-image-5.13.0-19-generic linux-modules-5.13.0-19-generic linux-modules-extra-5.13.0-19-generic

Same problem here with Ubuntu 20.04 on a Dell XPS 15 9500, but in my case it was triggered by update from kernel 5.11.0-38-generic to 5.11.0-40-generic.

Apt history shows the update as occurring last Friday morning, and the next time I rebooted (the day after) the WiFi module stopped working, message in dmesg as above. After the error, the WiFi module is not even visible to the BIOS.

The only way to get the WiFi module to appear again is to remove the back of the laptop and disconnect the battery, but if I boot Linux it immediately is knocked out again.

This issue has sat incomplete without any response from the reporter for more than 60 days so it is being closed as "Invalid" as it won't expire due to the linked bug watch.

However, the issue has probably been fixed as two of the three bug reports referred to in comment #3 are showing as being "Fix Released".

Please feel free to create a new bug report by issuing the command

  ubuntu-bug linux

in a terminal if this is still an issue when using a currently supported release of Ubuntu.
