LinuxQuestions.org - upgrade fc8 to fc9 gives white screen on reboot

strange thing happens to my FC8 ...

I have run Fedora Core 8 for some time, no probs.

Decided to upgrade to FC9...

yum -y upgrade

(800 packages later, ready for ...)

yum install preupgrade

(ran this and then 1 hour later a reboot was offered...all seems fine??)

rebooted.

this time GRUB offers a "upgrade to Fedora 9 (sulphur)

selected this, I eventually get a FEDORA splash screen which appears for about 10 seconds then the display goes white, bright white, nothing else. Mouse frozen. No disk activity. No modem activity? Nothing. Just frozen. Cannot <ctrl-alt-backspace> or anything?? Had to press power button to reset the box. ohhh err!

the GRUB line added to menu.lst is:

Code:

title Upgrade to Fedora 9 (Sulphur)

        kernel /upgrade/vmlinuz preupgrade lang=en_US.UTF-8 keymap=us stage2=hd:sda1:/upgrade/stage2.img method=http://www.mirrorservice.org/sites/download.fedora.redhat.com/pub/fedora/linux/releases/9/Fedora/i386/os

        initrd /upgrade/initrd.img

weird? any ideas good folk?

if I boot my old kernel, all is well.

Has the upgrade been successful? How would I tell? I dont think it has gone too well?
