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.
