Dropped RX - Intel 82576+Ubuntu Server 12.04.1
Всем пятницы!
Сервачок на платформе Supermicro. Сетевуха на чипе Intel 82576 (Dual port) интегрированная. Установлена чистенькая Ubuntu Server 12.04.1. Все обновления конечно установлены. Наблюдается следующая проблема: растет счетчик RX dropped

Счетчик RX dropped медленно, но верно растет. Патч-корды менял, пробовал разные - и фабричные и самопальные. Свитчи менял - HP, Cisco, DLink, 3Com... Компилил дравер из исходников. Все равно счетчик RX Dropped не равен 0 и растет. Установил чистенькую CentOS 6.3 - и о чудо! Счетчик RX Dropped = 0 и не растет.
Собственно вопрос: кто виноват и что делать? Виновато ядро 3.2.0-31-generic? Убунтий - корпоративная политика, переехать на другой дистрибутив не могу.
