In several days I discovered that DMA is turned off on my HDD (fsck
sayed it while Debian booting). Please, help me turn on DMA mode.
My hardware:
motherboard: Epox 8RDA3I rev 3.3 (nForce 2 Ultra)
hdd: WD1200JB (ide, 120gb)
cpu: Sempron 2200 (k7)
My software:
Debian lenny
kernel: linux 2.6.24-1-686
bootloader: grub 0.97-41
Today I upgraded my linux kernel to 2.6.25-2-686, but problem hasn't
been solved yet.
This is important information: the vendorID (10de NVIDIA) and the
deviceID (0065 NVIDIA_NFORCE2_IDE). You will get the same information by
running "lspci -nn" on the command line; it will be listed as
"[10de:0065]". This IDE controller seems to be supported by the amd74xx
driver in kernel 2.6.25 (according to the Debian driver check page at
http://kmuto.jp/debian/hcl/).
The first thing to check is if your kernel loaded the correct modules;
please post the output of this command:
lsmod | grep -E 'amd74xx|ata|\bide'
Also, install the "hdparm" package if you don't have it already and run
"hdparm /dev/hda" as root. What response do you get? You can also try to
turn on DMA yourself with "hdparm -d1 /dev/hda"; maybe you will receive
a helpful error message.
I installed hdparm long ago and it says that dma if off, moreover hdparm
can't turn it on:
leva:/home/anthony/admin# hdparm -d1 /dev/hda
/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
Trying to check if my kernel has loaded the correct modules:
leva:/home/anthony/admin# lsmod | grep -E 'amd74xx|ata|\bide'

Also I'm giving you output of 'lspci -nn' command:
