私は最近、HP MicroServerリモートアクセスカード615095-B21を搭載したUbuntu 14.04 LTS（Linux 3.16を実行）で動作するオフサイトバックアップにHP Microserver N54Lを使用しています。サーバーに接続した後、dmesg（およびそれ以降のsyslog）は次のメッセージでいっぱいです。

リモートアクセスを使用しても画面に直接接続しても、カードが正常に動作しているようです。これで、ログチェックホワイトリストルールを追加しても、少なくともメッセージがあふれません。しかし、メッセージが何を表しているのかわからず、1時間あたり何百ものログ行を削除したいと思います。
