In your command line: [ 0.000000] Command line: initrd=\EFI\nixos\c18phgd1m2qpc2g72pz14fg9h9i38j6w-initrd-linux-7.2.15-initrd.efi init=/nix/store/2m5ckvjrfdbcxrfpklc7rg16jwi11spa-nixos-system-nyx-26.11.20261106.4fe25e1/init usb-storage.quirks=0bc2:3343:u thunderbolt.host_reset=0 pcie_aspm=off nohibernate root=fstab loglevel=4 lsm=landlock,yama,bpf Please drop thunderbolt.host_reset=0 and pcie_aspm=off. The later disables much more than just ASPM so it may affect everything. Once you have done that please take another dmesg (and check also the link registers via tbdump).
