You are not logged in.
After pacman -Syu I could no longer log into my system neither via GDM nor on tty.
I found the culprit to be pam, after downgrading it via chroot everything works fine. The upgrade would be (1.3.1-2 => 1.5.0-2)
For the time being I have
IgnorePkg = pam
in my pacman.conf. But this is not a solution. I guess I need to edit the configs.
My encrypted /home partition unlocks at gdm-login (a behaviour I might extend to tty if this makes solving the problem easier).
Adding here /etc/pam.d/system-login

When upgrading, did you have a pacnew file in /etc/pam.d ?
P.S. - pam 1.3.1 was released last May. You did not run pacman since then?

known issue. See here https://bbs.archlinux.org/viewtopic.php?id=258358 (and probably many other threads).
