DMA problems



I can't get DMA working at all on my dual G4 tower. When I try to turn it
on with hdparm (hdparm -d1 /dev/hda) I get errors on the console and it
gets turned off again. Is there some module I should have loaded? This is
really distressing; my swap partition is on this non-DMA drive, so things
get VERY SLOW when I do anything memory-intensive (like running KDE,
Kaffeine, xchat, mozilla, gaim, and several xterms all at once). Please
help!
