FC6->FC7 Kernel Panic

[Tod]

I'm attempting to upgrade one of my servers from FC6-FC7 on the way to 
FC8.  I followed all the recommendations including the disk LABELs, etc 
and everything seemed to work.  But once I rebooted I got a kernel panic 
because my /boot directory can't be found.

I have two IDE drives both LVM managed except for a small boot partition 
on the first drive.  I can boot back to FC6 just fine, but get the 
kernel panic when I try the FC7 kernel.  My grub.conf looks like this:


# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,0)
#          kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
#          initrd /initrd-version.img
#boot=/dev/hda

title Fedora (2.6.23.15-80.fc7)
         root (hd0,0)
         kernel /vmlinuz-2.6.23.15-80.fc7 ro root=LABEL=/boot
         initrd /initrd-2.6.23.15-80.fc7.img
title Fedora Core (2.6.22.14-72.fc6)
         root (hd0,0)
         kernel /vmlinuz-2.6.22.14-72.fc6 ro 
root=/dev/VolGroup00/LogVol00 hdc=ide_scsi
         initrd /initrd-2.6.22.14-72.fc6.img


After the first time I booted I changed the FC7 kernel line, it 
originally looked the same as the FC6 line.  That didn't help.  My fstab 
looks like this:

/dev/VolGroup00/LogVol00 /                      ext3    defaults        1 1
LABEL=/boot             /boot                   ext3    defaults        1 2
devpts                  /dev/pts                devpts  gid=5,mode=620  0 0
tmpfs                   /dev/shm                tmpfs   defaults        0 0
proc                    /proc                   proc    defaults        0 0
sysfs                   /sys                    sysfs   defaults        0 0
/dev/VolGroup00/LogVol01 swap                   swap    defaults        0 0
LABEL=SATA1             /mnt/sata1              ext3    defaults        0 0
LABEL=SATA2             /mnt/sata2              ext3    defaults        0 0

The bottom two entries are partitions I have on a supplemental SATA drive.

sfdisk reports this:

   for C/H/S=*/255/63 (instead of 3148/16/63).
For this listing I'll assume that geometry.

The ERROR's gave me pause, but I'm booting FC6 ok.  Could this be the 
problem?

Any advice would be great.  I can post more information if it would help.
