Isn't it more a matter of having a CF card that does do DMA and a controller that does DMA, but a CF to IDE adapter that does not do DMA? If it is really a case of a CF card that claims to do DMA but is unstable if you try (I have found one model that does so), then it should simply be added to the ide dma blacklist instead.
Maybe I will try this also, but for the moment it is running.
I blacklisted 'SMART CF' on my system since they have random read errors and other i/o errors whenever DMA is enabled (while other cards work fine with DMA enabled). They claim to do DMA, but sure don't seem to do so reliably on this system. SiliconDrive CF works perfectly with DMA on the same system.
It is working now with "hda=nodma" on kernel 2.6.24-rc5. Thanks to Bartlomiej Zolnierkiewicz who gave me the hint to use the newest kernel.
