[pkg-cryptsetup-devel] Bug#792552: still doesn't continue shutdown process

[Pali Rohár]

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!
