Рандомно отключается WiFi на ноутбуке при большой нагрузке на канал. Например скачивание файлов, торрентов и т.д. Но при этом бывали дни, когда всё работало без сбоев. Проблема наблюдается независимо от роутера, места и прочих условий. Расстояние от роутера 1 метр. Использую network-manager 0.9.10.0. Перезапуск его сервиса позволяет заново подключиться к сети. dmesg в момент отключения:

Читал, что это может быть как-то связано с энергосбережением pci, но это направление ничем не помогло. Сталкивался ли кто-нибудь с проблемой и удалось ли её решить?
