Почему kernel usb для внешнего диска делает disconnect, а затем connect?

Question

Добрый день

 

Keenetic II  2.16.D.9.0-1

К роутеру по USB подключен бокс на два диска и одна флэшка, на которой OPKG packages

Роутер самопроизвольно 2 раза в день через день (по наюлюдению за логом за 4 дня) делает следующие действия (лог ниже)

В чем причина, как это убрать? Просто не вижу смысла в том, чтобы он будил диски - зачем лишний износ и потребление энергии?

Спасибо

Крайне странное поведение. В наличии два носителя, flash&hdd и оба "спят мёртвым сном", если не обращаюсь к ним принудительно. Возможно в вашем случае, есть внешние раздражители, читайте сервисы. Всякие там торренты, либо какой-то демон из entware...
