LinuxQuestions.org - Cannot use fc 9 kernel after upgrade from fc 5 to fc 9

Halo, anyone here ever upgrade Fedora Core 5 to Fedora Core 9?
It's been 2 days now that I've been trying to upgrade. Here are what I
did :

# yum clean all

# yum update

then I got info that libcrypto.so.6, libssl.so.6 & libtermcap.so.2
which was needed by ckermit package and mozilla = 37:1.7.13-1.1.fc5
(it really had the equal sign) which needed by mozilla-devel was not
installed. When I checked, looks like libcrypto.so.6, libssl.so.6 &
libtermcap.so.2 are inside openssl-0.9.8a-5.4 package so I query the
installed rpms

# rpm -qa|grep openssl

# rpm -qa|grep mozilla

and I got that openssl-0.9.8a-54 and mozilla-1.7.13-1.1.fc5 was
already installed.

So I removed ckermit and mozilla-devel then do another yum update
again and this time everything went well, total approximate download
were 2 GB.

I left my laptop all night to download and install and in the morning
everything had completed, the display was not the usual fc 5 anymore
but when I restarted my laptop it still access to fc5.

# uname -a
Linux xxx.xxx.com 2.6.20-1.2320.fc5 #1 Tue Jun 12 18:50:38 EDT 2007
i686 i686 i386 GNU/Linux

Boot option check gave me the information that fc9 exists. Below is
what's in /boot/grub/menu.lst:

title Fedora (2.6.25.4-30.fc9.i686)
root (hd0,4)
kernel /vmlinuz-2.6.25.4-30.fc9.i686 ro
root=/dev/VolGroup00/LogVol00 rhgb quiet
initrd /initrd-2.6.25.4-30.fc9.i686.img

title Fedora Core (2.6.20-1.2320.fc5)
root (hd0,4)
kernel /vmlinuz-2.6.20-1.2320.fc5.i686 ro
root=/dev/VolGroup00/LogVol00 rhgb quiet
initrd /initrd-2.6.20-1.2320.fc5.img

when I force to use fc 9 I got these error message :

Unable to access resume device (/dev/VolGroup00/LogVol01)
mount: could not find filesystem '/dev/root'
setuproot: moving /dev failed: No such file or directory
setuproot: error mounting /proc No such file or directory
setuproot: error mounting /sys: No such file or directory
Mount failed for selinuxfs on /selinux: No such file or directory
switchroot: mount failed: No such file or directory

Inside /boot there are already kernel fc9 files such as
config-2.6.25.4-30.fc9.i686, initrd-2.6.25.4-30.fc9.i686.img,
System.map-2.6.25.4-30.fc9.i686 and vmlinuz-2.6.25.4-30.fc9.i686

/etc/fstab seems ok

finally I tried to update once again in text-mode:

# yum clean all

# yum update

there are about 150 MB files to download and after that there are lots
of add-on for mozilla installed, which I never add it previously.

Try to install kernel again:

# yum install kernel

and I got info that the latest kernel version already installed.

Anyone know what's the problem and how can I use fc 9? Thx.
