I think it has something to do with the fact that the initrd
of Debian kernels use cramfs so the kernel probably expects the
initrd of lvm to be using cramfs and since it's not, it fails to
read what's inside the initrd.

I'm not sure how you can instruct a kernel to not expect a cramfs
initrd.
When you use the Debian tools to make an initrd, it's possible to make
an initrd without cramfs. One can use the following in the
mkinitrd.conf file:

     MKIMAGE="genromfs -d %s -f %s"
