Running into an issue when trying to switch to the latest kernal. I add the lines boot.kernelPackages = pkgs.linuxPackages_latest; to my config and when I rebuild the system I get the error:
error: builder for '/nix/store/yv8d9l9xwrm7frncjra2gqw750z50yln-linux-6.8-modules-shrunk.drv' failed with exit code 1;

Seems like its related to my VFIO so Ill post my vifo config below:
{ config, pkgs, lib, ...}:

];
in {
options.vfio.enable = with lib;
mkEnableOption "Configure the machine for VFIO";
config = let cfg = config.vfio;
in {
boot = {
initrd.kernelModules = [
"kvm-intel"
"kvm-amd" # Some guide reccomended that I use boot.kernelModules = ["kvm-amd kvm-intel"] but that does work and this does. Maybe look into it later.
"vfio_pci"

"vfio_iommu_type1"

kernelParams = [
