2.5.39: hdparm: HDIO_SET_DMA failed: Operation not permitted

[Olaf Dietsche]

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 
brw-rw----    1 root     disk       3,   0 21. Jul 1998  /dev/hda/0

$ /sbin/hdparm -V
hdparm v5.2
