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 ?

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

[Martin Pitt]

Hello all,

Yesterday we found quite a fundamental flaw related to how D-Bus is
stopped during shutdown [1]. It might be worth a try to edit
/lib/systemd/system/dbus.service and append these two lines to the
[Service] section:

  ExecStop=/bin/true
  KillMode=none

Then run systemctl daemon-reload as root. Does this improve shutdown
for any of you?

Note that this is certainly not a magic bullet for all kinds of
shutdown problems, especially since the reports/data here is vague
enough that these might very well be different reasons. But it would
be interesting to see if it makes a difference for any of you. The
Ubuntu bug https://launchpad.net/bugs/1427672 was linked to this
Debian one and found to be fixed with the above D-Bus change.

Thanks,

Martin

I think this also happens to me now and is reproducible.
ii  systemd215-5+b1 amd64system and service manager

Here is a screenshot:
https://www.unix-ag.uni-kl.de/~bloch/.debian/IMG_20140923_215621.jpg

If I press Ctrl-Alt-Del while it is in hanging state, it attempts to
restart a couple of tasks, see picture. If I do that twice withing a
second, it prints FAILED messages. Looks totally crazy. 

Regards,
Eduard.

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

[Aquila Rubra]

I booted already with systemd.log_level=debug systemd.log_target=kmsg
log_buf_len=1M enforcing=0

On shutdown, nothing is printed. At once, as the command is given,
everything disappears and the screen turns to black. There is no
apparent activity. It just stays like that.

 Up to 20 minutes.

 Yes, it happens always. I cannot turn off the computer any longer. I
 reinstalled Wheezy, upgraded again to Sid, and it happened again. It
 did not happen one month ago with the previous dist-upgrade. I use
 amd64 with lxde.

 Can you follow the instructions from [1] and get us a debug log from the
 shutdown

 sync  reboot -f works

 (The debug.sh script needs to be saved under
 /lib/systemd/system-shutdown/ in Debian, not /usr)

 /shutdown-log.txt is not even created.

 If you enable verbose mode, what is the last message you get?

 This is the last thing I get from syslog.

 If you can access the debug shell on tty9, what processes are running
 (ps aux) and what's the output of systemctl list-jobs.

 No console is accessible. The disks do not spin. It just stays like
 that without powering off.

 Can you boot with systemd.log_level=debug and create a screenshot with a
 camera to see the last message that is printed by systemd on shutdown.

Can you drop the systemd.log_target=kmsg and try again.

Can you also attach the output of all your installed packages,
a systemd-analyze dump and journalctl -alb dump

thanks.
