Non-free firmware not loaded after update

Help
1

Hi,

today I updated my nixos installation with

boot.kernelPackages = config.boot.zfs.package.latestCompatibleLinuxPackages;

set. With this update there was a kernel update from 6.6.50 to 6.10.10. When I now boot the new kernel it is identified as

Linux zellat2nix 6.10.10-gnu #1-NixOS SMP PREEMPT_DYNAMIC Tue Jan  1 00:00:00 UTC 1980 x86_64 GNU/Linux

and non-free firmware isn’t loaded anymore.

I don’t know where the -gnu suffix at the kernel is coming from and how I could use a normal kernel version with normal firmware loading.

Issue 341867 looks like the same problem. Does anybody has an idea how to fix it?

I just ran into this as well running my system against github:nixos/nixpkgs/8f7492cce28977fbf8bd12c72af08b1f6c7c3e49' (2024-09-14) my config has the same option set:

boot.kernelPackages = config.boot.zfs.package.latestCompatibleLinuxPackages;

Ended up reverting for the time being.

same here with 24.05 and nixos/nixpkgs/8f7492cce28977fbf8bd12c72af08b1f6c7c3e49' (2024-09-14).

the temporary fix proposed in #341867 (comment):

replacing:
boot.kernelPackages = config.boot.zfs.package.latestCompatibleLinuxPackages;

with:
boot.kernelPackages = pkgs.linuxPackages_6_10;

seems to work!
