I'm guessing that your CF-to-IDE adapter doesn't have the correct lines
wired up for DMA to work properly, and the card indicates DMA support,
which libata tries to use but which doesn't work. It looks like it never
tried falling back to PIO after DMA failed. Seems like a deficiency in
the speed-down logic?
