Hi,
I'm using kernel 2.6.12.4 (vanilla), recompiled, on a Kubuntu, and when
I try to enable DMA, I get this error:
sudo hdparm -d1 /dev/hdc
/dev/hdc:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
I know that this typically means that the IDE chipset support is not
compiled in the kernel, but it is: I have this IDE
lspci | grep IDE
0000:00:1f.1 IDE interface: Intel Corp. 82801DBM (ICH4) Ultra ATA
Storage Controller (rev 01)
and so I have th module PIIX but the error still remains...
any clue, please?
thanks in advance
Lorenzo
