Right now the system panics.  phk@ refuses to investigate the bug at all 
(which is most unhelpful).  I can provide more detailed analysis of the 
problem on demand.

The patch changes the way that the 'unit == -1 && u != low' case is
handled.  It now leaves 'low' alone and tries the next device in the list 
rather than comparing 'u' against (-1 | extra).
