I have been trying to work out how to log a failed session with plymouth debug messages. I finally succeeded, it is attached. Note that at the end of log file, it goes into suspend. That was me trying to power off the machine, and not holding the button long enough. It actually suspends and resume right back to the stuck plymouth display, but I don't know any way out except to force the machine off.
