Ubuntu 20.04 LTS가 설치된 Dell PowerEdge R620이 있습니다. 시스템에는 Intel I350 NIC가 있습니다.
카드에는 4개의 이더넷 포트가 있습니다.
부팅 후 또는 정상적으로 실행되는 동안 이더넷 케이블을 포트에 연결하면 제대로 작동합니다.
임의의 지연(때로는 한 시간, 때로는 반나절) 후에 포트가 완전히 종료되고 깜박임이 완전히 멈춥니다.
- 이더넷 케이블을 뽑았다가 동일한 포트에 다시 연결해도 도움이 되지 않았습니다.
- 케이블을 다른 포트로 옮기면 됩니다. 따라서 이러한 지연 후에도 카드가 완전히 분실된 것은 아닙니다. 이 새 포트도 임의의 지연 후에 종료됩니다. 그러면 사용 가능한 포트가 2개 남습니다.
- 시스템을 다시 시작하면 4개의 포트가 모두 정상으로 돌아옵니다. 이를 사용하면 다음에 재부팅할 때까지 포트가 하나씩 종료됩니다.
실행하면 sudo lshw -C network다음과 같은 결과가 나타납니다.
