I can't get LAN work on new motherboard GA-970A-DS3P.
I've booted from minimal-amd64 and livecd-amd64 - the same problems.
But when I booted from minimal-x32 the LAN was working properly.
I made a diagnostic script to compare those system states and saw following differences:
Code: Select all
NETDEV WATCHDOG: enp3s0 (r8169): transmit queue 0 timed out
....
