Загруженность системы

[Maverik]

Когда в K3B режу диск система жутко грузится и тормозит. Так должно быть или здесь какаято засада?

[Rq.]

А DMA включен?

что говорит hdparm -d ?

[Maverik]

По всей видимости не включен. Если дело в дма то как его включить - пересобирать ядро?

Да, какбы BLK_DEV_IDEDMA должен быть включен в ядре.

[Maverik]

Думаю он у меня включен. Вот что видно в /usr/src/linux/.config
CONFIG_BLK_DEV_IDEDMA=y
CONFIG_BLK_DEV_IDEDMA_PCI=y
# CONFIG_BLK_DEV_IDEDMA_FORCED is not set
# CONFIG_IDEDMA_ONLYDISK is not set
# CONFIG_IDEDMA_IVB is not set

А сидюк у тебя, случаем, не скази? Или, может, эмуляция включена?

[3al]

[libastral mode on]
dmesg|grep 40-wire

[Maverik]

А сидюк у тебя, случаем, не скази? Или, может, эмуляция включена?

DWD-RW IDE
На счет эмуляции ХЗ - как проверить?

[Uncle_Theodore]

cat /proc/cmdline

Есть там какой-нибудь "hdd=ide-scsi"? Если есть, убери из lilo.conf и прогони lilo. Эмуляция больше не нужна.

[Maverik]

В /proc/cmdline пусто

[Uncle_Theodore]

На каком чипсете мать?
Что lspci говорит про IDE? Скорее всего, надо загрузить модуль вместо ide_generic
Возможно, придется пересобрать ядро.

Как модуль ,,,,,,мммм можно попробовать, ядро я еще не собирал ни разу.

как называется девайс?
/dev/sr? = scsi или эмуляция
/dev/hd[a-d] = ide
