No point bothering, it looks like it picks up the ff's at boot just fine like an unpopulated interface and things just work without any spurrious delay. I'll do a few more tests and will send the patches for review. Note that I had to do one change to libata-sff: --- linux-work.orig/drivers/ata/libata-sff.c 2009-12-01 16:51:10.000000000 +1100 +++ linux-work/drivers/ata/libata-sff.c 2009-12-01 16:52:59.000000000 +1100 @@ -2384,7 +2384,7 @@ void ata_sff_post_internal_cmd(struct at ap->hsm_task_state = HSM_ST_IDLE; if (ap->ioaddr.bmdma_addr) - ata_bmdma_stop(qc); + ap->ops->bmdma_stop(qc); spin_unlock_irqrestore(ap->lock, flags); I'll include that change in my patch series.
