Sorry, I didn't provide all the information.

I forgot to mention that I was using LVM on top of raid1.

I'll append the boot messages for the default kernel at
the end of the message.

My grub entry

  title XEN
      kernel (hd0,0)/xen.gz dom0_mem=262144 com1=9600,8n1
      module (hd0,0)/vmlinuz-xen root=/dev/system/dom0_root \
        selinux=0 splash=silent console=ttyS0  showopts
    module (hd0,0)/initrd-xen


Here is what my disk layout looks like

/dev/hda
  /dev/hda1   ext3   mounted on /boot in domain 0
  /dev/hda2   swap   unused at present
  /dev/hda3   software rsid

/dev/hdc
  /dev/hdc1   ext3   mounted on /foot in domain 0
                    (to boot from if /dev/hda is missing!)
  /dev/hdc2   ext3  unused at present
  /dev/hdc3   software rsid

/dev/md0      (/dev/hda3 + /dev/hdc3)

volume group 'system' using physical volume /dev/md0
  volume groups
  /dev/system/dom0_root    root filesystem for domain 0
  /dev/system/domU1_root   root filesystem for domain 1
  /dev/system/domU2_root   root filesystem for domain 2
  etc

grub installed in MBR's of both /dev/hda and /dev/hdc
and in /boot and /foot file systems.

I think it is not finding the volume groups because vgchange
in the init script can't read the physical volume /dev/md0.

If you wish, I could simply do away with LVM for testing purposes
and put the root filesystem on the bare /dev/md0 device.

I was expecting to see the value 232299648 in /sys/block/md0/size
This struck me as strange. There is enough of the raid stuff
working for you to see the /sys/block/md0 directory, but not
enough working to see a correctly reported size or an entry
corresponding to md0 in /proc/mdstat.

Here is the boot messages for the -default kernel:
Sorry it is a bit garbled. And yuk, escape sequences!
Perhaps this should be an attachment instead?
