Problem is still present in Stretch and cause system hangs at shutdown/reboot when using LUKS encryption. See: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=792552#153
Stretch has only version 232. As in Jessie is version 215 and according to first post this problem was introduced in 221, it is a regression when upgrading from Jessie to Stretch. Please fix this problem in Stretch. -- Pali Rohár pali.ro...@gmail.com
