Здравейте,
Машината е ASUS SK8N с nForce 3 150 със SuSE 10.1 и ядро 2.6.16.13-4. Имам
мрежов контролер на 3Com:
# lspci
01:06.0 Ethernet controller: 3Com Corporation 3c905C-TX/TX-M [Tornado] (rev 78)
Преди на негово място имаше контролер с чип на RealTek.
И с двата имаше един и същи проблем: системата забиваше при генериране на
известно количество трафик.
В syslog всеки път преди да зависне системата, има няколко стотин (може би)
пъти следните съобщения:

Въпросът ми е как да идентифицирам проблема и как да го оправя.
Ако има нужда от още информация, ще я предоставя.
Благодаря много!
Поздрави,
Митко
