F14->F15 preupgrade fails

[Kevin J. Cummings]

Today, I tried to upgrade my F14 test machine to F15.

Machine in question:  HP Pavilion 7490 desktop
			PIII w/512MB ram.
			Intel (something old) graphics

1st, I downloaded and burned (to a CD-R) the Live Desktop i686 CD.
	It boots in the CD drive and runs (in fallback mode).
	I got my first look at Gnome 3.  (oh boy)

2nd, I downloaded and burned the i386 install DVD to a DVD+RW.
	When I tried to boot it (from the machines DVD drive) it
        failed to boot.  Strange as the CD boots from the CD drive.
	(I'm about to try my x86_64 install DVD in this laptop just to
	see if its a problem booting from DVD+RW disks....)

3rd, I ran preupgrade, which sat and churned, and downloaded a bunch of
	packages, then announced it was ready to reboot.  When I
	rebooted, and selected the Upgrade to F15 entry, all I got was
	a blinking flat cursor in the upper left of my monitor.
	Nothing happens after that point.  I can give the 3-fingered
	salute to reboot the machine, and I can select one of the 3
	installed F14 kernels and the machine will reboot (into F14).

Here are the grub entries for the pre-upgrade and F14:

> title Upgrade to Fedora 15 (Lovelock)
> 	kernel /boot/upgrade/vmlinuz preupgrade repo=hd::/var/cache/yum/preupgrade ks=hd:UUID=f3299b81-9fc4-46eb-9189-a79591e894a1:/boot/upgrade/ks.cfg
> 	initrd /boot/upgrade/initrd.img
> 
> title Fedora (2.6.35.13-91.fc14.i686)
> 	root (hd0,0)
> 	kernel /boot/vmlinuz-2.6.35.13-91.fc14.i686 ro root=UUID=f3299b81-9fc4-46eb-9189-a79591e894a1 rd_NO_LUKS rd_NO_LVM rd_NO_MD rd_NO_DM vga=0x123 LANG=e
> n_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYBOARDTYPE=pc KEYTABLE=us noiswmd
> 	initrd /boot/initramfs-2.6.35.13-91.fc14.i686.img

The other 2 F14 grub entries are similar to the one above.

Can someone tell me what's wrong with the F15 upgrade entry (why won't
it boot?)  I've tried adding a root grub directive and a root= kernel
parameter entry, and neither of those changes makes a difference....

Do I need to add something?  Do I need to change something?

As I look at the 3 files in /boot/upgrade, they are all chmod 644.  As I
look at the kernel images in /boot, they are all chmod 755.  Should the
/boot/upgrade/vmlinuz file be changed to 755?

Inquiring minds want to know why preupgrade won't work for me!

Thanks for any/all advice!
