 On closer examination of the boot messages, there is a
 
   ahcisata0: BSY never cleared, TD 0x80
 
 a few lines before the "root device:" prompt, which probably explains
 why the root device was not found.  After reseating the SATA cables,
 the machine booted.
 
 The kernel still shouldn't crash, though, so there is still a bug
 somewhere.  Given that there are known bugs in the ahcisata error
 handling (kern/47097), maybe the condition that triggers the crash is
 not plugging in the keyboard at the root device prompt, but doing it
 after an ahcisata error.
