  Log:
  SVN rev 188464 on 2009-02-10 23:22:29Z by mav
  
  Check for device_set_devclass() errors and skip driver probe/attach if any.
  Attach call without devclass set crashes the system.
  
  On resume AHCI driver sometimes tries to create duplicate adX device.
  It is surely his own problem, but IMHO it is not a reason to crash here.
  Other reasons are also possible.
