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)
[...]
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.
