I'm using the same board (GA-990FXA-UD3) with the same ethernet card. I decided the onboard NIC was trash, so I installed a PCI ethernet card, installed arch, and started using it. Later, I went back to troubleshoot the NIC, and found that if I sudo pacman -Syu r8168; echo 'blacklist r8169' > /etc/modprobe.d/r8169_blacklist.conf; reboot; everything went okay, and no need for PCI card. I'm afraid that beyond that, I don't think I can help. Aaron
