Работа дисков SATA сопряжена с большой нагрузкой на процессор.

P.S. Могу и чушь прогнать, 2.6 ветку не пользую.

где?

На матери i875, я врубил соответственно PIIX.

В dmesg ничего нет по поводу дисков.

P.S. ПроблеМа.

А там, насколько помню, два варианта -- Silicon Image и Promise. Cyclon, попробуй включить и то и другое и пересобрать ядро.

> ASUS P4C800 возьми. Кроме нах не нужного RAID'а будет работать всё. Прям из коробки.

А насколько помню, SATA там как раз на RAID-контроллере болтается.

Нее эта хрень вызывала глюки с сидюком, я не мог включить ДМА на нём, т.е. я включил Enchance режим не Compatable и теперь на сидюке ДМА врубается а поведение дисков не изменилось.
