Public bug reported:
I am running Ubuntu 20.04.3:
$ lsb_release -rd
Description: Ubuntu 20.04.3 LTS
Release: 20.04
I am running Ubuntu on a Lenovo ThinkPad P14s with Intel Wi-Fi 6 AX210 Wi-Fi
interface. This used to work up to kernel 5.11.0-46 (which loaded iwlwifi
"firmware version 59.601f3a66.0 ty-a0-gf-a0-59.ucode op_mode iwlmvm").
Recently, Ubuntu auto-upgraded my kernel to first version 5.13.0-25 and then
5.13.0-27. Both of these kernel versions load iwlwifi "firmware version
63.c04f3485.0 ty-a0-gf-a0-63.ucode op_mode iwlmvm" and then my Wi-Fi interface
no longer works.
This is the error output from `dmesg` when running kernel 5.13.0-25:
