These messages do not come from the kernel. LVM2 is a userland thing;
the kernel only provides the building blocks for it (device-mapper).

I suspect this may be due to a difference in timing of device
initialisation. AFAIK initramfs-tools still doesn't know how
to handle asynchronous device discovery and relies on you to
fudge it with the 'rootdelay' parameter.
