In Fedora 19, after these messages appear booting hangs and never finishes.

ipv6: ADDRCONF(NETDEV_UP): enp2s10: link is not ready
nf_conntrack version 0.5.0 (16384 buckets, 65536 max)

The result is the same whether the network cable is plugged in or not. This issue occurs intermittently with different kernel versions. I tested other nic's as well as without any nic's with the same result.

Go into the settings for your network connection. (How you do that depends on your DE.) There will be a tab for IPv6. Under Xfce, I've selected to Ignore IPv6. You may need to tell it not to use it, or not to require it for a connection depending on how things are set up. Once you've saved that, you'll probably need to stop and restart your network connection to have the changes take effect, but once you do, you won't have to worry about it any more.

It happens to me sometimes, I have also one-time workaround.

Press ALT-F2 to switch shell
Login as root
Enter: killall gdm
After that, system should boot up

Don't forget to logout root.

If your ISP isn't using IPv6 and your connection expects it, your system will wait until either it gets the configuration data it needs or it times out. Telling it not to use IPv6 saves that time, and can cause a significant speedup in booting. And, if there's something wrong with that part of your networking software, this side-steps the issue by never invoking the problematic code.
