echo "options r8125 aspm=0" >> /etc/modules.conf
reboot
Same command works for both kmod-r8125 and kmod-r8125-rss variant.
Fixes instability and weird throughout issue for those who experience it. Have been struggling on x86 n100 system (asus pn43). Seems that issue depends on manufacturer settings.
Not needed for kmod-r8169, because it has it off by default (it doesn't support this modprobe option anyway).
I'm too lazy to push it upstream:)
