Hello

I have the same problem on a Asus k8 se deluxe running a 32bit sarge. My ide hda and hdc (dvd recorder) have no dma.

Mi 4 serial-ata disks do, but the ide one is the "system"  one and serial-ata ones are only for data.

Here is my /proc/ide/via for you to compare it. I do not see any problem on it
