 I have now compiled and run it.  It does not appear to help.  On cold
 boot (powerup), it happened to work properly (wd0 and cd0).  On subsequent
 reboots ('shutdown -r now'), it would alternately fail, then work, then
 fail again.

 Again, on my system the spurious 'wd1' should be atapibus0 and cd0.
 Perhaps the new "timeout" message addition will provide a clue?
