Fwd: Debian Stretch, no password prompt for luks-encrypted home partition during boot

I have system with soft raid and /home is encrypted (one of raid1 partitions is encrypted using luks with password). When I boot it using default boot kernel options (ro quiet) systemd stops on waiting for partition, but no any password prompt. I try to boot with plymouth (ro quiet splash), but it does not help me. I may boot only using "recovery mode". In this case system asks me for password and I may enter it (but there are lot of kernel messages after prompt).

update-initramfs finishes without errors or warnings.

What I'm doing wrong?

Best regards,
