[pkg-cryptsetup-devel] Bug#875642: /sbin/cryptsetup: blocked in semop on shutdown waiting for already terminated systemd-udevd

Package: cryptsetup-bin
Version: 2:1.7.3-4
Severity: normal
File: /sbin/cryptsetup
Dear Maintainer,
Since my setup is going to need keyscripts, I have installed sysvinit-core
shotrly after upgrading to Stretch.
Since then, "Stopping crypto disks..." hangs indefinitely on shutdown while cryptsetup
is blocked in semop() syscall. Once I managed to call shutdown from single-user mode
and pressed Alt-SysRq-E once it hung, which caused recovery shell prompt to appear;
thus I got the attached backtrace.
My other Stretch computer also has sysvinit-core and cryptsetup with keyscripts
but doesn't have this problem despite having encrypted root.
How do I debug this problem?
