I am currently running 2.6.18-1.2869.fc6 without any issues. I then rebooted my machine to find that there was a different kernel (2.6.18-1.2869.fc6xen), it proceeded to load and got to udev (where it says "ok" in green) and right at the point where it would go to GUI, everything stops responding. Any idea what could be wrong? Thanks, Nick
