:  Modified files:
:    sys/kern             subr_bus.c 
:  Log:
:  Don't let DS_BUSY buses block attachment of other devices.
:  DS_BUSY implies that the device has been in state DS_ATTACHED
:  before, so we need include DS_BUSY buses in the search as well.

    Well, want to test this as much as possible, keep a close watch on your
    boot messages.  If I remember right the origial DS_BUSY on busses was
    an attempt to prevent recursion loops which could occur due to the
    BIOS listing both master and slave busses.
