> Thanks for clarifying - as you say, the spec is specific to PCI. > Our silicon has its own host interface which was confused by a length of zero ! You aren't the first. If you look at the current tree you'll see we now have ata_dumb_qc_prep() for interfaces that think 0x0000 is zero. Set that as your qc_prep method and set sg_tablesize in the driver to LIBATA_DUMB_MAX_PRD and it should work (we have to use a smaller sglist limit as the worst case is now 2 entries per 64K block) - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
