I see errors in the journalctl output.  Look into these:

Sep 12 19:41:12 myhost systemd-vconsole-setup[84]: /usr/bin/setfont failed with error code 71.
Sep 12 19:41:12 myhost systemd-vconsole-setup[84]: ...................
Sep 12 19:41:12 myhost systemd-vconsole-setup[84]: setfont: putfont: 512,8x16:  failed: -1
Sep 12 19:41:12 myhost systemd-vconsole-setup[84]: putfont: PIO_FONT: Invalid argument
Sep 12 19:41:12 myhost systemd-vconsole-setup[117]: /usr/bin/setfont failed with error code 71.

Sep 12 19:41:13 myhost systemd[1]: [/etc/systemd/system.conf:15] Unknown lvalue 'TimeoutSec' in section 'Manager'

The former errors might be normal on a system with no VGA, and you 
mentioned seeing this over serial.  Do you see those errors on systems 
that boot normally?  Do any of those system share a hardware 
configuration with the system that doesn't?

The latter error seems more likely to be the cause of the emergency 
shell, but that's a guess.
