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:

hdd: WD1200JB (ide, 120gb)
cpu: Sempron 2200 (k7)

Today I upgraded my linux kernel to 2.6.25-2-686, but problem
hasn't been solved yet.

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)

Hopefully there will be an error message somewhere that clears this up a
little. Try to reboot and then run:
dmesg | grep grep -Ei 'ata|ide|amd74xx'
Furthermore, there could be relevant messages very early in the boot
process; you might have to use ScrollLock plus pen and paper to catch
them (or set up logging to a serial console).
I have tried command "dmesg | grep -Ei 'ata|ide|amd74xx'", suggested by
you (after rebooting and logging in console (nor kdm that I use
usually)).
Please read output in the attachment. Thank you for help.

Some driver (ide_generic?) takes control of the devices before libata is
loaded. Check the output of "cat /proc/interrupts" to see which module
has IRQs 14 and 15.

The nforce2 driver cannot take ove rthe devices => no DMA.
I can think of a few more things to try, but I don't know how "safe"
they are:
- put amd74xx as the first non-comment line into /etc/modules
- boot with "blacklist=ide_generic" appended to the kernel command line
- likewise, try "libata.dma=3" at boot (may be dangerous)
- check the kernel documentation for "libata.force=..." (can be really
dangerous)
- check if the amd74xx module is included in your initrd:
zcat /boot/initrd.img-$(uname -r) | cpio --quiet -t | grep -E
'(ide|ata|amd)[^/]*\.ko'
- build your own kernel with amd74xx compiled in
I have already tried first three things you had given me higher
(/etc/modules; "blacklist=ide_generic" or "libata.dma=3" in the kernel
command line). But none of them have solved me problem.
Now, my /etc/modules file looks:
[EMAIL PROTECTED]:~$ cat /etc/modules
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.
# Parameters can be specified after the module name.
amd74xx
loop
My main boot record (that I usually use) in /boot/grub/menu.lst looks:
title Debian GNU/Linux, kernel 2.6.25-2-686
root (hd0,2)
kernel /boot/vmlinuz-2.6.25-2-686
root=UUID=683f90cf-5af5-4946-b90d-c69541f15966 libata.dma=3 ro
initrd /boot/initrd.img-2.6.25-2-686
savedefault
Please, correct me if I have done something wrong.
amd74xx module seems to be included in my initrd:
[EMAIL PROTECTED]:~$ zcat /boot/initrd.img-$(uname -r) | cpio --quiet -t |
grep -E '(ide|ata|amd)[^/]*\.ko'
