As suggested in another thread, i've downgraded from 2.6.19 to 2.6.18, but im still having problems with DMA and my HDD. Its really causing a lot of performance issues.
I've tried setting the DMA using hdparm, but it says it can't be done. Weird this was, it was enabled with the 2.4.33 kernel (Default slack11 install).
Is there a kernel parameter I may be missing?
Error when trying to set dma
Code:
root@slack:~# hdparm -d1 /dev/hda
/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
Heres the output from hdparm
Code:
root@slack:~# 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 = 65535/16/63, sectors = 120103200, start = 0
and the HDD info
