Public bug reported:
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:
[EMAIL PROTECTED]:~# 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
[EMAIL PROTECTED]:~# 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.
