Bug#763028: systemd-sysv shutdown and reboot hang system

[Tim Ruehsen]

Hi,

just want to state that I am struck by this bug for a while now.
Just started today searching for a solution.

No change in behavior at all.

Hmm, from my reading they say (in the end) "Don't do that !".
But however, it didn't solve anything here, so I removed the two lines.

I waited for a timeout a complete night, nothing happened. I have to tip the 
reset (hardware) button or press the poweroff knob for 5s.

What works is ALT + PrintScreen + REISUB.

But still my filesystems (several VMs running) are broken from time to time 
(e.g. one of the ReiserFS VMs needs a fsck.reiserfs --rebuild-tree, else it 
denies booting).

I have Samba installed (but can't uninstall it for testing), no squid 
installed.

I am on Debian SID amd64 (up-to-date packages).

What exactly can I do to help fixing this bug ?
