Boots up but no login (Tosh 4005cds 4.6-RELEASE)

I tried to upgrade my laptop from 4.3-snap to 4.6-RELEASE by
renaming /usr/src and changing the target in options/Release Name
to 4.6-RELEASE
I choose a non-X developer in bundle selection and chose ftp as media.

The upgrade completed and on reboot there is no file named /kernel.
Only /kernel.prev and /kernel.GENERIC so at the boot prompt I said:
boot /kernel.GENERIC.

It boots up but when I finally get to the login prompt there is no
response to anything I type.  No other virtual terminals are
available either.

The last few bootup messages I see say:

Login: []

The cursor is not blinking and no typing is recognized.

What can I do here to get started and see what the trouble is?  I
don't recognize the messages, but the previous install (4.3 snap) had
sendmail installed.
