Can't enable DMA
I can't enable DMA on my distro. I've used hdparm -d1 /dev/hda and it comes with an error saying that it is not allowed, it doesn't have permissions to do it. I've tried enabling DMA with the kernel menuconfig but in the end it just doesn't work... i can i fix this?
My distro lags a bit every time i do something like executing a program or something that uses the disk.
