The problems i found in the past was not with the compact flashs, but with ide/cf adapters. I have many bulk adapters with name "CFDISK IDE/CompactFlash adapter" from PC Engines GmbH. With revision 1D i can't get DMA works, with rev. 1E instead works very well and fast. On the board, visually, there are no differences.
