I wonder if this is related to the recent RNG changes. It seems that
many programs have started using blocking RNG functions like
getentropy(), and now that the kernel is more conservative in its
initial entropy estimation they can block for a long time. Keyboard or
mouse input adds entropy.
At a guess, plymouth is starting the X server and the X server wants
random bits for MIT-MAGIC-COOKIE authentication.
