Hi! I am trying to get dma to work with hdparm (system is VERY slow 
without it), but when I
do 'hdparm -d1 /dev/hda' I get this:

 settings using_dma to 1 (on)
 HDIO_SET_DMA failed: Operation not permitted
 using_dma   =   0 (off)

I am building blfs on top of an LFS 6.0 System. On SuSE dma works fine. 
How do I fix this?
