I think Hugh traced it down to a unrelated timer change. The above really wants to wait for BUSY clear, perhaps the best solution would be to have piix device its own ata_piix_device_resume() that first waits for BUSY clear, then calls ata_device_resume().
Close... all devices should wait for libata to signal that the bus is ready to be talked to. For some that's waiting for BSY to clear, for others that's checking the SATA bus.
