Fixed in libbsd/0.8.7-1.1 on unstable: https://tracker.debian.org/news/958795/accepted-libbsd-087-11-source-into-unstable/"Switch Linux getrandom() usage to non-blocking mode, continuing to use fallback mechanims if unsuccessful. Closes: #898088"
I installed libbsd0_0.8.7-1.1_amd64.deb on a buster VM and it no longer hangs after lightdm credentials are entered (the xfce4-session hang reported in #899080):
