HP Z2 G1a does not support PCIe ASPM on Debian Linux

[Idontknowyet]

Hi,

please help. I`m running Proxmox 9.1.2 on my HP Z2 G1a and can not activate PCIe ASPM:

root@pve:~# journalctl -b | grep ASPM
Dec 17 16:23:45 pve kernel: ACPI FADT declares the system doesn't support PCIe ASPM, so disable it
Dec 17 16:23:45 pve kernel: acpi PNP0A08:00: _OSC: OS supports [ExtendedConfig ASPM ClockPM Segments MSI EDR HPX-Type3]
Dec 17 16:23:45 pve kernel: acpi PNP0A08:00: FADT indicates ASPM is unsupported, using BIOS configuration
Dec 17 16:23:45 pve kernel: r8169 0000:c1:00.0: can't disable ASPM; OS doesn't have ASPM control

In BIOS I can not find any settings. I want the system to draw a bit less power than 16W on idle state. The CPU only uses C1, C2 and C3. Most of the time C3.

Before I was using Windows, where the same configuration was drawing 3-5W when idle.
