iwlwifi module crash on load for M.2 Intel AX210 NGW WiFi Card

[c10l]

I've recently purchased an M.2 Intel AX210 NGW WiFi Card and installed it on one of my PVE hosts. When the iwlwifi module loads, it crashes:

Turns out this microcode requires the file iwlwifi-ty-a0-gf-a0.pnvm to be present in /lib/firmware along with the microcode files themselves. Unfortunately it seems that this file is not present in pve-firmware:

root@pve0:~# dpkg -L pve-firmware | grep iwlwifi-ty-a0-gf-a0.pnvm
root@pve0:~#

It is present on Debian's firmware-iwlwifi package but if I try to install that, apt tries to remove the kernel and other core PVE packages:

root@pve0:~# apt install firmware-iwlwifi

Do you want to continue? [Y/n]

For now I manually downloaded the file from the the upstream kernel tree and it's working but it would be better to have the file included in PVE's firmware package.

Thanks mate! I was looking for a solution about his issue!

Thanks this helped. I also download the ibt-0041-0041.sfi firmware for bluetooth to work but I'm still getting an error saying Failed to load Intel Firmware file intel/ibt-0041-0041.sfi (-2).

I downloaded the latest firmware (currently linux-firmware-20221109.tar.gz) from kernel git, then extracted it running "tar -zxf linux-firmware-20221109.tar.gz", get into the extracted folder and copy all to the firmware folder via command "cp -ax * /lib/firmware". I shutdown the server and restart. Hopefully, it will also work for those who use AX210. Source for this tip: https://github.com/spxak1/weywot/blob/main/ax210.md#install-new-firmware

Confirming that this also worked for me but with a completely different wireless card (Intel Centrino Ultimate-N 6300, model 633ANHMW, inside a Dell M4600 laptop). dmesg reported that it couldn't load iwlwifi-6000-4.ucode. It was indeed missing from /lib/firmware. I then downloaded and unzipped linux-firmware-iwlwifi-fw-2022-11-08.tar.gz from https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/linux-firmware.git/ and only moved iwlwifi-6000-4.ucode into /lib/firmware/. After a reboot the kernel module loaded and the wifi adapter came up. I noticed that a lot of files in /lib/firmware were xz compressed, but apparently this is not a requirement. Just copying the .ucode file was enough to get it to work.
