This bug arises because the 'details' plymouth splash plugin, which plymouth falls back to by default, is missing a display_message function -- plymouth tries to display the prompt informing the user about the filesystem mount problem but the message is silently discarded in the absence of this function.
This was also affecting any system using a 'console=...' kernel parameter, as plymouth falls back to the 'details' theme in this case (and probably in others too).
A patch to add the missing function is attached. I will publish fixed packages in a PPA shortly (I have verified that they fix the problem in the serial console case, in a Xen VM). I also reported this bug upstream: https://bugs.freedesktop.org/show_bug.cgi?id=29035
