저는 최근에 HP MicroServer 원격 액세스 카드 615095-B21을 장착한 Ubuntu 14.04 LTS(Linux 3.16 실행)로 운영되는 오프사이트 백업을 위해 HP Microserver N54L을 사용합니다. 서버에 연결한 이후 dmesg(및 이후의 syslog)는 다음 메시지로 가득 차 있습니다.

원격 액세스를 사용하든 화면에 직접 연결하든 카드가 제대로 작동하는 것 같습니다. 이제 로그 확인 화이트리스트 규칙을 추가하여 적어도 메시지가 넘쳐나지는 않을 것입니다. 하지만 메시지가 무엇을 나타내는지 전혀 모르고 시간당 수백 개의 로그 줄을 삭제하고 싶습니다.
