Yes, this seems to confirm my suspicion that something is blocking by 
calling getrandom without GRND_NONBLOCK.

The situation you describe does not implicate plymouth, because the 
pause occurs after you enter your credentials. This is a tricky one, 
because it could be lightdm, or systemd which is a known offender, xorg, 
or anything else in your session. This is a tricky problem to diagnose 
because, as soon as you start typing, your login will complete. I 
suggest reporting this against lightdm to get maintainer advice. The 
Debian Xfce and lightdm maintainer has commented on #897572 and is aware 
of the getrandom issue, but I could not find any lightdm issue for it.

Which iso image did you use to install testing?

Kind regards,
