Estou executando o Arch Linux. No dmesg eu tenho as seguintes mensagens:
[ 3.225860] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready
[ 8.405807] e1000e: eth0 NIC Link is Down
[ 39.495793] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready
[ 44.679494] e1000e: eth0 NIC Link is Down

[ 115.709482] e1000e: eth0 NIC Link is Down
[ 344.245735] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready
Estou realmente usando o IPv6 neste link (ele se conecta a um modem a cabo) e eu preciso desse link para ficar pronto. Observe que o "não pronto" não é um problema de passagem breve. Não fica pronto até que eu o traga manualmente.
Eu tive que substituir a placa-mãe após um relâmpago. Depois de fazer isso, o eth0 (o da placa-mãe) não aparece automaticamente, mas as 4 portas da placa PCI Intel (Adaptador de Servidor Ethernet I340-T4) aparecem. A placa-mãe possui um Intel Ethernet (I219-V). (Veja a saída lspci abaixo.)
Eu tentei o seguinte sem sucesso:
netctl reenable eth0-profile
Esse link ainda não aparece automaticamente. ip a mostra que este link está ABAIXO. netctl status mostra uma falha:
netctl status eth0-profile

Warning: Journal has been rotated since unit was started. Log output is incomplete or unavailable.
Executar este próximo comando manualmente não dá sucesso:
netctl start eth0-profile
Este sistema tem nunca uma unidade systemd ativada para [email protected] (ou até mesmo um serviço dhcpcd genérico de todas as interfaces). Eu não sou contra a adição de um, se isso resolver, mas funcionou antes sem ele e eu gostaria de voltar ao estado anterior. (Eu tenho snapshots do btrfs, mas não quero retroceder. Quero entender o que está acontecendo e fazer as correções, então aprendo algo com isso.)
Para resolver o problema do meu link, tenho que executar os seguintes comandos.
sudo ip link set eth0 up
sudo dhcpcd -n eth0
sudo systemctl restart dnsmasq
Depois de executar esses comandos, tudo está bem. Por algum motivo, ele não está sendo iniciado automaticamente. Ao executar esses comandos, percebo que ip link set eth0 up leva muito tempo. Às vezes eu tenho que executá-lo várias vezes.

UPDATE 2
Ainda não encontrei uma solução. Adicionar essas duas linhas ao / etc / netctl / eth0-profile pareceu resolvê-lo por um tempo, mas o problema retornou.
TimeoutUp=300
TimeoutCarrier=300
Encontrei algumas informações novas. Após a inicialização mais recente, os registros mostraram esses problemas:
Sep 12 03:38:26 arch2 network[358]: Duplicate Address Detection is taking too long on interface 'eth0'
Sep 12 03:38:27 arch2 network[358]: Failed to bring the network up for profile 'eth0-profile'
Sep 12 03:38:27 arch2 dhcpcd[588]: script_runreason: /usr/lib/dhcpcd/dhcpcd-run-hooks: Terminated
Eu posso trazer a rede assim:
# netctl restart eth0-profile
depois disso, tudo está funcionando. No entanto, gostaria de encontrar e resolver o problema subjacente.
Aqui está a saída do status do systemctl "netctl @ eth0 \ x2dprofile.service"
