Работа дисков SATA сопряжена с большой нагрузкой на процессор.

Ты все-таки покажи кусок конфига ядра в разделе ide.

Хм, а какой там чипсет, не Silicon Image случаем? Тогда

CONFIG_BLK_DEV_SIIMAGE=y

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

> Хм, а какой там чипсет, не Silicon Image случаем? Тогда

где?

На матери i875, я врубил соответственно PIIX.

Действительно, там не SI (посмотрел на asus.ru), а ICH5R. По такому поводу выдержки из dmesg, касаемые дисковой системы -- в студию.

В dmesg ничего нет по поводу дисков.

Странно, перечитал тут все - все правильно и должно работать.

Я знаю что должно :) вот только проблемма имеет место 8) быть :(

Есть только одна мысль - контроллер SATA на матери вместо ICH... какой-то другой. Больше ИМХО просто нечему быть.

P.S. ПроблеМа.

> Есть только одна мысль - контроллер SATA на матери вместо ICH... какой-то другой.

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

Во, цитата из fido7.ru.linux (обсуждение, какую материнку брать).

> 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.

А у тебя SATA винты случаем не в совместимом режиме работают (в BIOS смотри)? Типа на IDE отображаются. Так вроде такие проблемы и должны наблюдаться.

У меня SATA вообще нет.

> А у тебя SATA винты случаем не в совместимом режиме работают (в BIOS смотри)? Типа на IDE отображаются. Так вроде такие проблемы и должны наблюдаться.

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.

А нагрузка до 40% это нормально? Если стоит reiserfs на обоих дисках.
