NO.
I used IDE DMA all the time with 1.3.x and 2.0.x kernels, enabled by hdparm. I have never had a problem, even with two WD drives under heavy load.
Mark's IDE driver works well for the vast majority of people. Right now, my disk throughput is way down because I can't enable DMA, even with hdparm. I don't see the point in disabling DMA for everyone just because of a few problems which might not be caused by the IDE driver in the first place.
Back to lurk mode...
