Description scaramouche 2019-11-26 22:53:25 UTC

Starting with a raspberrypi0_defconfig, then selecting 
Toolchain/C library = glibc
System configuration / Init system = systemd
the device boots normally, but the welcome message and the login are shown twice.
Trying to login with 'root', a password is then request, even if not set in the configuration.
After entering 'root' and a blank password twice, the device block and it is no more possible to continue.

Here's a piece of the bootlog:

[   13.773714] bcm2835_v4l2: module is from the staging directory, the quality is unknown, you have been warned.
[   13.835338] bcm2835_codec: module is from the staging directory, the quality is unknown, you have been warned.

Sorry, long standing inconvenience with the rpi/systemd combination, see e.g. [1], [2] for description/solution...

(In reply to scaramouche from comment #0)
Luckily in the intermittent, you can fix this bug by changing "console" to "ttyS0" under System configuration ---> Run a getty (login prompt) after boot ---> TTY port
