The LUKS part seems to succeed as you can access decrypted volume and see it's 
lvm2. And the LVM part doesn't work. Did you try a manual pvscan/vgscan after 
you get into the fallback shell?

And I neither know your setup nor how LUKS/LVM works behind the curtain in 
detail, but CONFIG_DM_UEVENT may be important to trigger exactly the step you 
seem to be missing.
