yes, there seems to be a problem with the autofs4 mounts.

I just found a way to boot into a working system with an x86_64 kernel
and a x86 userland by omitting all automounts!

1.) boot into systemd emergency mode
2.) start all *.mount points that have an corresponding *.automount
unit:

i.e.:
# systemctl start dev-hugepages.mount
# systemctl start dev-mqueue.mount
# systemctl start proc-sys-fs-binfmt_misc.mount
# systemctl start sys-kernel-debug.mount
# systemctl start sys-kernel-security.mount

(make sure to not have any automount in your /etc/fstab (with
comment=systemd.automount)

3.) start graphical target

# systemctl start graphical.target

This will boot into a working system at least with my Fedora 15
installation.
