    kernel - Fix apparent timing race in early usb keyboard polling code
    
    * Fix an apparent timing race where a USB command does not complete
      prior to the poll issued with the command.  Perform another poll
      in a loop to deal with it.
    
    * Problem appears to occur w/ohci's early poll prior to ehci attachment.
