After my upgrading my kernel to 5.8.1 (from 5.7.9) nmcli no longer lists wifi networks
$ nmcli device wifi list
$
lspci shows:
$ lspci -k | grep -i wireless
00:14.3 Network controller: Intel Corporation Wireless-AC 9462
Subsystem: Intel Corporation Device 0000
Kernel modules: iwlwifi
Though I can only see my ethernet interface:
$ ip link
1: lo: <LOOPBACK,UP,LOWER_UP> ;...
2: enp0s20f0u2: <BROADCAST,MULTICAST,UP,LOWER_UP> ...
Kernel logs show something wrong with my iwlwifi firmware:
$ dmesg | grep iwlwifi
[ 1.441490] iwlwifi 0000:00:14.3: no suitable firmware found!
[ 1.443057] iwlwifi 0000:00:14.3: minimum version required: (efault)108
[ 1.444592] iwlwifi 0000:00:14.3: maximum version supported: (efault)105
[ 1.446207] iwlwifi 0000:00:14.3: check git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
[ 1.447704] iwlwifi 0000:00:14.3: Couldn't request the fw
[ 1.449863] iwlwifi: probe of 0000:00:14.3 failed with error -2
FWIW this I can see all the latest iwlwifi kernel drivers:
$ ls /lib/firmware | grep iwlwifi-9000
iwlwifi-9000-pu-b0-jf-b0-33.ucode
iwlwifi-9000-pu-b0-jf-b0-34.ucode
iwlwifi-9000-pu-b0-jf-b0-38.ucode
iwlwifi-9000-pu-b0-jf-b0-41.ucode
iwlwifi-9000-pu-b0-jf-b0-43.ucode
iwlwifi-9000-pu-b0-jf-b0-46.ucode
The troubleshooting guide for iwlwifi suggests installing linux-firmware-iwlwifi-git but it looks like its out-of-date compared to the kernel drivers I see in linux-firmware
And yes I have linux-firmware installed:
$ pacman -Qi linux-firmware
Name : linux-firmware
Version : 20200721.2b823fc-1
Any thoughts on how I should proceed here?
Edit:
Also noticed my bluetooth stopped working and not sure if its related:
$ sudo bluetoothctl
[bluetooth]# power on
No default controller available
$ rfkill list
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no

I'm also affected, needed to run linux-lts to make it work again.
I didn't try to dig through kernel logs, but to me, the adapter was present in UI and tried to connect to devices without success, or it was kinda connected, but wasn't able to do anything with the audio device.
Is there any bug report already?

Looks like it's fixed in 5.8.2

I've tried both 5.8.2 and 5.8.3 and dmesg still shows the same errors in the logs.
