Решил сам: вынул батарейку BIOS, что позволило сбросить его на начальные настройки.
После перезагрузки перестал подниматься сетевой интерфейс eth1 - это встроенная сетевуха

В системнике две сетевухи - одна отвечает за Инет, другая за раздачу его через точку доступа. При перезагрузке Арч нагло меняет их местами и приходится перевтыкать штекеры. Что делать, чтобы Арч больше не шалил?

Периодически начинает висеть Plasma - ни виджеты, ни панелька не работает. Стало после обновления. Примерное время зависания минут 10-15, затем всё становится нормально минут на 20-30 и по новой. Идеи?
Профессор, ты не прав. Торрент как раз с него и качаю. Остальные компы в доме с виндой.
Машина действительно раздаёт инет, просто за ней работаю ещё и я. (:

Нет ни одного открытого торрент порта (6881-6889). Пытался через iptables открыть 6888 - получил жилище индейцев (фиг вам).

Да заковырялся уже. Deluge с той же песней.
По ходу порты намертво закрыт (:

Порт стоит 6888.

Для открытия порта делал команду
sudo iptables -A INPUT -p TCP –dport 6888 -i eth0 -j ACCEPT
