[SOLVED]No suitable firmware found for iwlwifi - kernel 6.16.5-arch1-1

Hello,

I have two mini PCs with the same hardware. I updated the one to  kernel 6.16.5-arch1-1 but now the iwlwifi module fails to load because of missing firmware. Bluetooth also does not work. The WiFi and Bluetooth on the PC that is still running kernel 6.16.4-arch1-1 is working fine.

Installed kernel and firmware packages

• linux 6.16.5.arch1-1

• linux-firmware 20250808-1

Output of of the lspci -s 00:14.3 -vnn command:

On the 6.16.4-arch1-1 kernel, it loads the iwlwifi-so-a0-hr-b0-89 firmware, but on the 6.16.5-arch1-1 it is looking for the iwlwifi-so-a0-hr4-b0-89 firmware which does not exist.

Re: [SOLVED]No suitable firmware found for iwlwifi - kernel 6.16.5-arch1-1

So this is fixable by simple downgrading the kernel?

Re: [SOLVED]No suitable firmware found for iwlwifi - kernel 6.16.5-arch1-1

I downgraded the kernel to 6.16.4-arch1-1 and had the same problem after restarting. I then shut it down again and this time I removed the power and this resolved the issue on the 6.16.4-arch1-1 kernel. I then upgraded it again to the 6.16.5-arch1.1 kernel and the WiFi and Bluetooth are now working again.

Output of dmes on the 6.16.5-arch1-1 kernel.
