Linux 6.18.7 firmware load issue

Help

Hi :waving_hand:

I got a weird issue after latest upgrade: Wifi (intel/iwlwifi) stopped working. After checking dmesg, I saw the error no suitable firmware found!in it. If I remove the module and re-load with modprobe, it works again.

Here is the relevant dmesg output, which you can see it starts with usual warnings after some time when I do the reload:

I don’t have any changes in my config, and always had linux-firmware installed (hardware.firmware = [pkgs.linux-firmware]and hardware.enableRedistributableFirmware = true).

Is there a recent change which broke my old config, e.g. a new option which I should use instead? I tried to check latest commits on nixpkgs but nothing strike me as direct suspect, so I am not sure if this should be a github issue instead.

Thanks!

This kind of thing is most likely a kernel bug, presumably there was a kernel version bump. You can try switching to newer/older kernels to confirm.

A firmware/BIOS update can also sometimes solve stuff like this.

This is redundant, by the way, pkgs.linux-firmware is redistributable.

You can see what the option does by the way by using the option search (NixOS Search), and clicking on “Declared in”:

Thanks, I removed the hardware.firmware one :light_bulb:

I was not expecting this could be a kernel bug tbh, I thought something is wrong with module loading order in initrd or similar :smiley:

But yes, now overriding the version to 6.18.6 again, it works. Looks like an issue with latest version (6.18.7).

Thanks again!
