Bug Description
I just bought a new motherboard[1] and CPU[2], and now DMA doesn't work for my IDE drives:
root@emperor:
/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)

Just to make sure I don't get things confused - you have a SATA motherboard, but your hard drive is still connected via traidtional IDE, right?
