Why 512 words ?
Though I have queued Mark's patch to be applied, my gut feeling would lean towards a single DRQ block, rather than 512.

Why not just work from the old IDE code.

 	ata_altstatus(ap);
-	ata_chk_status(ap);
+	ata_drain_fifo(ap, qc);
ap->ops->cleanup();

might be wiser
If someone needs that, they can override the error handler with their own. No need for a new op.

PDC202xx needs

Alan, you're the expert there (my condolences!).
Can you generate a fix for the PDC202xx to go with this?

Cheers
