[CentOS] Boot hanging with rhgb

Hello

I have installed Centos-4.1 and love it over Fedora or Mandriva. A big thank you to all the hands and minds that have put together a very good distribution. However I do have a problem when I boot with rhgb enabled in grub.conf. The system hangs at the end loading IE(when the bar is full). I can get bye in either of two ways. The first is to switch to a virtual console before the system hangs and the other is to remove the rhgb option in grub.conf. I would ask for any comments on how to trouble shoot this problem so it can be fix. Or if it is not important please tell me and I will remove the option from grub.conf. Thank you in advance for your help.
