Re: Странная проблема с ADSL
Провел небольшой эксперимент на машинке с дебиан: вынул батарейку с МП
+ сбросил биос. Когда зашел первый раз без настройки биоса lspci
показывал обе карты - встроенную в МП (которая был отключена из-за
глючности) и новую на чипе риалтека. Но вот когда я отключил
встроенную в биосе, lspci стал показывать только ее. Я так понимаю мои
подозрения о том, что МП подгорела, начинают оправдываться?... Стоит
ли бежать за PCI-E сетевухой или большая вероятность, что будет такой
же результат?
Привожу все команды с этой же неработающей машины на дебиане и ниже с
работающего ноута.

С работающего ноута на дебиане:
Повторение команды ip где-то через 10-15 секунд после первой. Вывод
tcpdump примерно за 2-3 минуты.
