hdparm -d1 /dev/hda failed

[gustavo halperin <ggh.develop@gmail.com>]

Hello

I updated yestarday my kernel from 2.6.15.1 to 2.6.17.8.  I used almost 
the same .config with a little more new modules from the new kernel.
Now, my Hard Disk, that is the /dev/hda have the dma off and I can't 
change it. See below
/> hdparm -d1 /dev/hda
/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma    =  0 (off)/

I search for the same problem in the net and I fine something about some 
"via". I have many compiled i2c_via and i2c_viapro compiled like module. 
See below:
/> grep via /proc/modules
i2c_viapro 8916 0 - Live 0xf0d58000
i2c_via 4548 0 - Live 0xf0d55000
i2c_algo_bit 9992 5 
i2c_voodoo3,i2c_via,i2c_savage4,i2c_prosavage,i2c_i810, Live 0xf0d02000
i2c_core 22352 17 
lm90,eeprom,i2c_isa,i2c_viapro,i2c_sis96x,i2c_sis630,i2c_sis5595,i2c_piix4,i2c_nforce2,i2c_i801,i2c_amd8111,i2c_amd756,i2c_ali15x3,i2c_ali1535,i2c_algo_bit,i2c_algo_pcf,i2c_dev, 
Live 0xf0d23000/

Any idea what is the problem here??

Thank you,
