Tere !

Tegemist on CentOS-i ja Linux 2.6.18 kerneliga.
Emaplaat: MB Intel 1xXeon S3200SHV

Probleem selles, et IO-support-i saan 32 bitisena tööle, aga ei saa DMA-d tööle.
Nagu hetkel mõistan ei saa OS kontraga hakkama, aga kuidas seda saada tööle ?

Praegune seis:

Kernel on pakist ja mitte ise tehtud? Kusagil .18 versiooni paiku olid kerneli ide/sata/scsi süsteemis suured ümberkorraldused. Tasuks proovida mõnda uuemat kernelit, milles eeldatavasti tolm veidi settinud. Abi oleks ka lspci väljundist.

Inteli kontrollerid võiks edukalt töötada, aga midagi leidsin siit:
http://www.linux-archive.org/gentoo-user/220150-extremely-slow-sata-ide-interface-intel-corporation-82801i-ich9-family.html
Kuna sul on 2 erinevat sata kontrollerit, tasub võibolla ka proovida ketta liigutamist ühe küljest teise külge.
Võimalusel, jätkuvalt, tasub proovida ka uuemat kernelit.
