In libata specifically, we remain peppered liberally with a bunch of msleep()'s all over the place, particularly when dealing with SATA phys. 10ms here, 20ms there, 200ms in sata_link_resume(), it all adds up when you're talking about fast boot.

For most hardware, we can scan ports in parallel, which gets you past the biggest annoyances, but not all of them.
