проблемы с включением DMA [ SOLVED ]

Привет народ.
Есть такая проблема... никак не хочет устанавливаться режим DMA, все опции которые нашёл в ядре, включил, бесполезно.
Вобщем вот что имеем:

# hdparm -d1 /dev/hda

/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)

# dmesg | grep hda

hda: Maxtor 6Y080P0, ATA DISK drive
hda: max request size: 128KiB
hda: 160086528 sectors (81964 MB) w/7936KiB Cache, CHS=65535/16/63
hda: cache flushes supported
hda: hda1 hda2 < hda5 hda6 hda7 hda8 >
Adding 522072k swap on /dev/hda6. Priority:-1 extents:1
EXT3 FS on hda7, internal journal
EXT3 FS on hda8, internal journal

# hdparm -I /dev/hda
