No, the debian kernels enable DMA by default. If you don't get DMA it almost always means the ide-generic driver is being used rather than the driver for your specific chipset. The generic driver can't do DMA since DMA requires specific knowledge of the chipset. > Well, I have an MSI K9A Platinum, with the SB600 controller.

I know 2.6.20 had some more patches to fix some issues with that chipset. If you are running 2.6.18 that Etch uses then I would expect problems like this. 2.6.21 from Sid might work better. In general I recommend avoiding ATI chipsets in the first place. > I'm uncertain about any kernel configuration items I might want to > activate.
