I have the same problem when running the live "CD" off a quickly discovered hard drive, and the persistent casper-rw on a slower USB drive.
In scripts/casper:mountroot() the livefs_root is waited for, but once it's found the casper-rw drives are probed for without waiting, which in my case fails since the USB drive appears some seconds later.
