ifconfig + device interrupt
what is the — device interrupt 90 memory 0x434000000-934fff from ifconfig command is it indicate on network problem ? , what we need to check on the OS linux ?
ifconfig -a RX errors 1971059972 dropped 503931 overruns 65 frame 1971059907 TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 device interrupt 90 memory 0x96000000-967fffff RX errors 0 dropped 0 overruns 0 frame 0 TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 device interrupt 102 memory 0x95000000-957fffff RX errors 0 dropped 0 overruns 0 frame 0 TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 RX errors 0 dropped 0 overruns 0 frame 0 TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 RX errors 0 dropped 0 overruns 0 frame 0 1 Answer 1
This is a very poor way to look for error information. Not every word with the string «err» in it means «error». The word «interrupt» just happens to contain «err». Not all output of the ifconfig command is error messages. It does, after all, report interface configuration.
if the answer is accepted, the question should be positive pointed. only good questions are answered agreed? else edit the question. i mean, if someone wants to know the answer, thats why they are here. Why should a users points be takes from the answer?? Something fundamentally wrong with that system.. So I upvoted question, and now i get negative points, what kind of socialist place is this?

Пару дней назад было возможно подключаться к Интернет через сетевой кабель, а вот сегодня система не видит eth0. При этом я не делал никаких обновлений системы или каких-то изменений в настройках.
Моя тема подобна этой: Решено: Настройка сетевой карты:не поднимается eth0. Но такое ощущение, что проблема в моём случае не с переименованием eth0, а с чем то другим.
Помогите, пожалуйста, разобраться и устранить (если возможно) проблему.
Вот что имеем:

On my system (OpenSUSE 11.4 — kernel 2.6.37) ifconfig indicates different interrupt number for eth0 than proc aqd sys file system. ifconfig indicates 17:
