Cannot enable DMA for my IDE-drive

[Erik Ridderby]

I'm running the Alpha-release of kubuntu feisty fawn and installed all updates.
When I try to enable DMA for my hardrives the command hdparm fails:

root@milo:~# hdparm /dev/hda

/dev/hda:
 multcount = 16 (on)
 IO_support = 0 (default 16-bit)
 unmaskirq = 0 (off)
 using_dma = 0 (off)
 keepsettings = 0 (off)
 readonly = 0 (off)
 readahead = 256 (on)
 geometry = 16383/255/63, sectors = 39070080, start = 0
root@milo:~# hdparm -q -m16 -q -W0 -q -d1 /dev/hda
 HDIO_SET_DMA failed: Operation not permitted

Nothing is written in dmesg

Thist happens on two of my sytsems and only in Kubuntu Feisty Fawn. Other Kubuntu-versions works fine.

Fails to upload the lsmod as attachment by some reason. Here it is as comment instead:
