Thanks for your quick reply and your debugging hints.
This afternoon I tried to reproduce the issues in a VM but
interestingly both didn't show up there (neither the missing modules
nor the lvm troubles). -- No idea which difference between the VM and
my real system is responsible here.
So I tried on my laptop now.
This is amd64 with the current 4.19 kernel from unstable, sysvinit,
luks+lvm on the internal SSD and an external (USB) disk.
Yesterday I downgraded udev to 239-15 and lvm2 to 2.02.176-4.1 to get
back a working system.
Now I first saved the ouptput of lsmod (attachment
lsmod.udev-239-15), updated udev to 240-2, turned on debugging
(udev_log=debug; hope that's correct?), and rebooted.
What I then found again was a massive amount of not loaded modules.
For comparison cf. attachment lsmod.udev-240-2.
No visible lvm troubles at that point.
Then I updated lvm2 to 240-2, and already at the installation I got:
#v+
Installing new version of config file /etc/lvm/lvm.conf ...
[....] Setting up LVM Volume Groups... WARNING: Device /dev/sda not initialized in udev database even after waiting 10000000 microseconds.
WARNING: Device /dev/dm-0 not initialized in udev database even after waiting
10000000 microseconds.
WARNING: Device /dev/sda1 not initialized in udev database even after waiting
10000000 microseconds.
[etc.]
#v-
After a reboot I got the exakt same WARNINGS at "Setting up LVM
Volume Groups..." during startup, and also on everything related to
lvm, like plain `lvs' etc.
Lines related to udev in the syslog are rare:
with old lvm2:

Maybe there's something anyone can make sense of … Sorry for not
being able to provide something clearer right now.
