Thread-topic: 3.4-testing : Kernel panic on bootup (mount: could not find filesystem /dev/root/)

I installed XEN 3.4-testing version without much problems in CentOS 5.3
running on quadcore Intel Nahelam processors using the following
steps (as in the README) :

hg clone http://xenbits.xensource.com/xen-3.4-testing.hg`
cd xen-unstable.hg
make world
make install
make linux-2.6-xen-config CONFIGMODE=menuconfig
make linux-2.6-xen-build
make linux-2.6-xen-install
mkinitrd -v -f --with=ahci --with=sd_mod --with=scsi_mod --allow-missing
cp initrd-2.6.18-xen.img /boot

After the installation, I updated the grub with the following entry :

title  Xen 3.4.2
        root (hd0,0)
        kernel /xen.gz loglvl=all guest_loglvl=all vtd=1 iommu=1
        module /vmlinuz- root=LABEL=/ apic=debug maxcpus=8
        module /initrd-2.6.18-xen.img
But during the bootup, I see Kernel panic with the only error above that
being :

mount: could not find filesystem /dev/root/
setuproot: moving /dev failed: No such file or Directory
no fstub.sys, mounting internal defaults
setuproot: error mounting /proc:No such file or directory

Is it an error in partition ? or a Grub entry error ?
Or an installation error ?

Can someone help me ?
