Update kernel to RHEL 6.6 boot progress bar freezes

Hi,

I updated the kernel to rhel 6.6. After restarting the server the boot progress bar now stops at the very end and the graphical environment does not start (i see this through iLO, my server is HP ProLiant). I can sucessfully login via ssh, if I type "startx" from there the graphical interface starts on iLO Remote Console and I can use it for the user that started it (weird???).

Any ideas on how I can make the graphical environment start normally, as it did previously?

Thanks for any help, I am really stuck on this one.

Kind Regards
