setting dma on on hdd

[juranj1]

hello,
i am sorry for asking you but i am a newbie:(...
i have a acer tm613txv nb, kernel 2.4.22
i would like to turn on dma on hhd but i get this message

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

when i use a kernel 2.4.20-8 that works fine
somewhere i founded that problem could be in driver Uniform Multi-Platform E-IDE
driver Revision: 7.00beta4-2.4 which is in 2.4.22, but i dont know how shoud i
solve this problem..thank you for every advice....(i think that i have compiled
everthing what i shoud)
