First, are you sure you actually have an RP board, or is it the MP? If
it's the latter, please select the MP support, as this will us totally
different IRQ vectors.

The other potential issue is if this is really an RP board, you're
probably being bitten by the bus-width problem on the CF slot vs what
libata expects it can do. We never bothered to work around this, since
the RP boards were never in mass circulation, so the solution there is
simply to disable pata_platform.
