FWIW I've just reproduced this in a ppc64el VM too. Console output:
Ubuntu Trusty Tahr (development branch) ubuntu hvc0
ubuntu login: hvc0 tty1 startpar-bridge startpar-bridge
This is definitely a behavior change from the previous version. (In fact, I upgraded plymouth in this VM specifically to check whether some other console issues were fixed, and have run into this instead.)
