In my case

sudo dmesg | grep ASPM
[    0.286094] acpi PNP0A08:00: _OSC: OS supports [ExtendedConfig ASPM ClockPM Segments MSI EDR HPX-Type3]
[    6.264745] r8169 0000:01:00.0: can't disable ASPM; OS doesn't have ASPM control

I guess I could try to use pcie_aspm=off in the grub, bt I don't know if this could have any side effects (I guess not)
