Entering a "?" or anything else so far results in

mountroot> ufs:/dev/da0a
panic: Root mount failed, startup aborted.
cpuid = 0
boot() called on cpu#0
Uptime: 1h59m17s

Thanks for the ideas.  I will try more when I get
home.  All I have available now is a serial console
(that sometimes is at 115200 baud and sometimes at
9600 baud) so I can't try anything other than various
iterations of root devices.

Please send any other ideas to try if you have them.
