I'm guessing that at this point in the boot process, geom hasn't reached the stage of being able to look at events and do something with them. I suspect that replacing g_waitidle(); with if (sc->type != MD_PRELOAD) g_waitidle(); will fix this problem; I'll test and commit this later. Colin Percival
