I have added
dm_mod
dm_log
dm_snapshot
dm_mirror
to 
/etc/initramfs-tools/modules
file and then 
did 
dpkg-reconfigure linux-image-2.6.30-2-686-bigmen
and it regenerated the initrd.img file
but then when I selected this kernel in grub2
it still could  not find the 
/dev/mapper/debian-root device.

I was dumped by grub2 into Busybox
(initramfs)
and when I ran
(initramfs) cat /proc/modules 

sure enough these modules were now in the kernel.
However when I did ls /dev/mapper all I see is
/dev/mapper/control
and I cannot find the
/dev/mapper/debian-root
directory
 
which exists when I boot into the vmlinuz-2.6.26-2-686  kernel.

So why is grub2 failing to boot in the 2.6.30-2-686 kernel?
