Cannot boot with raid1 and lvm since 3.2.0.0-bpo.1 and initrd 0.99~bpo60+1

[Peter Schaefer <peter.schaefer@gmx.de>]

Hello!

Since Kernel 3.2.4 (linux-image-3.2.0-0.bpo.1-amd64) and the
connected update of initramfs-tools to 0.99~bpo60+1 the initrd
is unable to mount the root filesystem.

I have to manually enter the following commands at the busybox
prompt:

 lvm pvscan
 lvm vgscan
 lvm lvscan
 lvm lvchange -a y /dev/vg00
 exec /scripts/local

The issue is independend from the kernel version, since it also
happens if i want to try the 2.6.32-bpo-5 image (that initrd got
updated, too).

Unfortunately, i don't know how to fix the issue and get lvm to
work automatically again and downgrading initramfs does also
remove the new kernel.

Regards,
 Peter
