Arch Linux

Description:

I've upgraded:
core/systemd
core/systemd-libs
core/systemd-sysvcompat

from version 241.93 to versione 242, and then i couldn't boot anymore.

Sometimes if from grub i start archlinux initramfs failback the boot works, but often i can't boot.
i've a LUKS encrypted SSD with ext4 file system

the boot hangs on "[ OK ] Stopped udev Kernel Device Manager."

Additional info:
* package version: 242
* kernel version: i've tested both 5.0 and lts version 4.19
* how to "fix": downgrade systemd (and -libs, -sysvcompat) to versione 241.93 fix the problem
sorry but i haven't some log or config files, because i don't know what can be helpful.
but i can provide it if you tell me what you need

Steps to reproduce:
simply starts ArchLinux after systemd upgrade,
but i've 2 pc, and only on notebook (i5 8250u) i had this problem, the desktop PC works fine (ryzen 5 2600)
