There might be race condition between plymouth-splash and plymouth-stop.

Normally the calling sequence should be:
plymouth
...
plymouth-splash
...
plymouth-stop

On the fail unit it looks like:
plymouth
...
plymouth-stop
...
plymouth-splash

Therefore the splash screen can't be displayed.

The timing that plymouth-splash would be executed relies on these conditions: (ref: /etc/init/plymouth-splash.conf)
  1) plymouth should be executed and,
  2) graphics-device-added or drm-device-added event has been emitted.

Condition 1 is always satisfied, so the possible reason of why plymouth-splash is not executed might be the graphic takes too many time to initial.
