yes indeed. On the certification page they talk about "I219-V". I didn't even notice that. That's a good clue.

hmm you describe exactly the same problem as I have. I am almost 100% sure this fix should help you too. Did you reboot your system with the new kernel setting? Did you check in /boot/grub/grub.cfg if the new setting pcie_aspm=off really is there after the reboot?
