[CentOS] CentOS 5.7 gives me a blank screen after bootup

Hi all,

I have an odd problem, for which I couldn't find any suggestions on google.

A CentOS 5.7x64 gives me a blank screen on bootup, both to the 17" LCD
monitor connected to the VGA port, and to the KVMOVIP device
built-into the server,

I can see the GRUB boot loader, and everything booting up, upto the
point where it says "Waiting for driver initialization.", then it goes
blank - both on the LCD and the KVM.


Does anyone know how to fix this?

It does the same whether I boot into the CentOS, or XEN kernel, or in
single user mode.

First few lines of /etc/grub.conf:


#          initrd /initrd-version.img
#boot=/dev/md0
default         0

timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
