Comment 3 for bug 1908140

> your bonded links are down; nothing will happen until they are brought up.

Yes, I figured as such. I've already tried to bring up eth0, eth1, and bond0 via ip, ifup, and ifconfig to no success.

> your pasted log appears incomplete since i see no output for eth0 or eth1; please paste or attach your entire log.

This is the entire log since reboot. If I look at the journal from previous boots, there are mentions of eth0 and eth1, as well as eno1 and eno2.

$ networkctl list
IDX LINK TYPE OPERATIONAL SETUP
  1 lo loopback carrier unmanaged
  2 eno1 ether off unmanaged
  3 eno2 ether off unmanaged
  4 eth0 ether off pending
  5 eth1 ether off pending
  6 bond0 bond no-carrier configured
  7 docker0 bridge no-carrier unmanaged

After doing ip link set dev {eth0,eth1} up, they change from off to degraded in networkctl list. Attempting the same on bond0 afterward does nothing.

$ networkctl status -n 40
* State: no carrier

All of the lines from today (Dec 15) correspond to my attempts to bring interfaces up as mentioned above, then bringing them back down after it failed.

It seems there's a naming conflict between the eth and eno devices. udevadm test-builtin net_id ... shows both enp3sf0 and enp5s0f0 should be eno1 and enp3sf1 and enp5s0f1 should be eno2
