Can you `boot -c' to enter userconf and disable mfii? > boot -c userconf> disable mfii userconf> quit If that works, can you file a PR about mfii(4) hanging with no disks? I wouldn't be surprised if that's an edge case that nobody developing the driver had tested. It's probably just a matter of a missing xs->error = XS_WHATEVER; scsipi_done(xs) somewhere, maybe conditional on `if (sc->sc_doesn't_actually_have_disks_plugged_in)'.
