Hi Grobhack,

Regarding your issue, can you check the status of ASPM in BIOS? Below is the steps:

Access the BIOS> Go to Advanced and then Integrated IO configuration.

Use down arrow keys to select PCIe Misc. Configuration Under Integrated IO configuration.

Press enter key to view the options in PCIe ASPM Support (Global).

Select Disabled and press enter to select the option.

Press F10 to save and Exit.

Also, you can try steps in this link : https://www.intel.com/content/www/us/en/support/articles/000092564/graphics.html

Please let us know the outcome.

Additionally, please share the ssu logs for us to investigate further.

It seems to be working now after changing the bios setting

01:00.0 Ethernet controller: Intel Corporation Ethernet Controller X550 (rev 01)
LnkCap: Port #0, Speed 8GT/s, Width x4, ASPM L0s L1, Exit Latency L0s <2us, L1 <16us
LnkCtl: ASPM L1 Enabled; RCB 64 bytes, Disabled- CommClk+
01:00.1 Ethernet controller: Intel Corporation Ethernet Controller X550 (rev 01)
LnkCap: Port #0, Speed 8GT/s, Width x4, ASPM L0s L1, Exit Latency L0s <2us, L1 <16us
LnkCtl: ASPM L1 Enabled; RCB 64 bytes, Disabled- CommClk+

I have attached some pictures of the bios settings.

I am still only reaching package c-state c2 but thats probably nothing to do with the Ethernet Controler

Solution: the thing that fixed it for me was a reboot and reseting the bios and setting the the required settings again, they were set before, but setting them again fixed it for me.

I also have run powertop --auto-tune but i'm not sure if it's part of the solution, also i have a kernel parameter set for pci_aspm.policy=powersave but same as for powertop i'm not sure if this is part of the solution, just saying it to show the complete picture.
