Bug#877672: Acknowledgement ([systemd] System Stalled at Pam-nologon)

[David Baron]

More experiences with this problem:

When I get the error, not possible to log in. Must poweroff using the power 
button, hold until stop.

If the CPU is not abnormally hot (usually will not be), then rebooting will 
usually proceed normally.

Doing this reboot using a sysvinit bootup shows no relevant warnings or 
errors.
