Since you did an upgrade, there is a chance that something is wrong
with the SELinux config. Try turning off SELinux enforcing mode
by running this command:

 	echo 0 > /selinux/enforce


If that makes your problem go away, you can either permanently turn
off enforcing or relabel the file system.

To change the SELinux behavor, edit /etc/sysconfig/selinux and reboot.

To relabel the filesystem, this should do the trick:

 	restorecon -R /


If turning off SELinux doesn't fix it, can you provide us with a
little more info? Otherwise we're mostly just guessing.

* contents of /var/log/gdm/*.log
* your config (one NIC or two NICs, etc)
* unusual output from "dmesg"
* anything interesting in /var/log/messages, /var/log/secure, etc.
