Hi,

with 2.5.39 I get the following error (2.5.40/www.kernel.org is
unavailable at the moment):

# hdparm -d 1 /dev/hda/0

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

It works with 2.4.14. I haven't tried any other.

$ ls -la /dev/hda/0
