I am unable to enable dma on a hard disk that I know supports it.

Code Sample

hdparm -d1 /dev/hda
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = (off)

yes I am sudo-ed bash. yes I know it supports dma. I previously had this machine successfully running gentoo linux (with dma) and I can mount it that way from knopppix.

also maybe this has something to do with it?

in the console (virtual terminal)

Code Sample

Autoconfiguring Devices... *spinner* modprobe: modprobe: can't locate module block-major-2
