Ноутбук Asus M50Vc проблема cdrom

[Alexz]

Уже писал, но тема заглохла. Отключается cdrom во время, работы. Вставляю диск, он монтируется, дальше начинаю с ним работать и спустя некоторое время привод отключается, то есть диск крутиться а в Убунте его как-будто нет. Причем не реагирует на команду извлечения eject, ни на umount, ни на кнопку открытия лотка. Спасает только выключение ноута. Стоит Ubuntu 9.04, ядро 2.6.28-13.
Вот что показывает dmesg

И ещё. Пользуюсь 3G модемом от Билайн (HUAWEI E160G). Подключается нормально, но если не пользоваться активно интернетом, например только pidgin висит, то он переходит в автономный режим и соединение разрывается. Как это можно исправить, чтобы он работал постоянно?

[Hugin]

У меня была таже проблема, возникала с DVD дисками.
Выставил в BIOS-е опцию Advanced –> IDE Configuration –> SATA Operation Mode в Compatible и проблема ушла
