  Log:
  SVN rev 182998 on 2008-09-13 15:17:23Z by marius
  
  MFC: r182688
  
  Bypass isa_probe_children(9) and directly call bus_generic_attach(9)
  in order to avoid the invasive probes done by identify-routines of
  ISA drivers, which may access unassigned addresses or those of
  unrelated devices and thus in turn can trigger master/target aborts
  as revealed by r182108 and ahc(4). I think that this is also the
  cause of the hang previously seen on B100 blades during boot.
  Bypassing isa_probe_children(9) also avoids adding ISA hints, which
  just can be wrong for sparc64.
