Отпечатай - Не мога да подкарам dma на харда

Тея дни си купих Toshiba Satellite A200-1hv. Веднага се впуснах в инсталиране на Gentoo на него, но имам проблеми със подкарването на DMA-то на хард диска. Нека започна от lspci:

Направих малко проучване в google и видях, че точно така трябва да е сетнато.

ето и uname -a:

което е адски бавно.

Рових много из нета и нищо полезно не намерих и почвам да се отчайвам. Някой има ли идея как да подкарам DMA-то?

Ако сменя драйвъра със новия SATA driver вобще не проработва и ми дава грешка още при boot че не може да монтира root fs via NFS.
