I figured it out (with the Adafruit cable): I had an outdated NFS entry
in /etc/fstab which now pointed to nothing, and it is automatically
mounted so it runs before the login prompt and sshd. So that pretty much
disabled non-serial logins if I had the network cable connected.

The serial console gave enough information to fix the problem and to
restore /etc/ttys to the original settings.
