linux-image-3.9-0.bpo.1-amd64 efistub fails to activate LVM

[James Robertson <j@mesrobertson.com>]

I decided to use this kernel on my laptop and use efistub.

Upon boot it drops to BusyBox complaining it cannot find / which is on
a logical volume. (/boot is on a standard partition).

If I run "vgchange -ay" it detects my logical volumes, I can then exit
the initramfs prompt and it then continues to boot fine.

I tried adding rootdelay=30 to the arguments but this didn't help.

The efibootmgr command I am using is:

efibootmgr -p 2 -c -g -L "Debian (EFI stub)" -l '\EFI\debian\vmlinuz'
-u root=/dev/vgtWyRt3/root ro quiet rootfstype=ext4 add_efi_memmap
initrd=\\EFI\\debian\\initrd.img

vmlinuz and initrd.img are copied to the efi partition as follows:

cp /vmlinuz /initrd.img /boot/efi/EFI/debian/

One thing I have noticed is that when I am in the BusyBox prompt I can
"ls /dev/vgtWyRt3/" and only swap shows up.  So the swap parition
which is also an logical volume IS detected - making my subject line a
half truth I guess...  All the rest of the logical volumes are EXT4
and fail to get detected until I run vgchange.

The system is multibooting with Windows 8.

Below is my LVM and mount info.
