Same problem there. I have up-to-date Debian Stretch with LUKS-encrypted rootfs and system hangup on every shutdown or reboot.
I debugged this problem and found out that after this log message [....] Stopping remaining crypto disks... is called cryptsetup luksClose <disk> And cryptsetup itself freeze. When I patched init script to call cryptsetup with -v --debug args I see there these last lines: # Udev cookie 0x.... (semid ....) decremented to 1 # Udev cookie 0x.... (semid ....) waiting for zero So it looks like problem is in cryptsetup and bug is still there! -- Pali Rohár pali.ro...@gmail.com
