Jaunty - Wireless issue causes laptop shutdown to hang indefinitely

[w3wsrmn]

As of Jaunty, when attempting to shutdown my laptop, it hangs indefinitely at:
Deconfiguring network interfaces...

It seems to be a wireless issue, as the laptop will shutdown normally if connected via wired.

If connected to wireless at shutdown, hangs.
If disconnected from wireless, but radio on, hangs.

[Charles Profitt (cprofitt)]

I found that in my situation if I do a:

sudo ifconfig wlan0 down

and then shutdown it resolved the issue.

Can you try this and see if it resolves your issues. Thanks.

[Charles Profitt (cprofitt)]

I also verified that turning wireless off via bios results in the same results as reported here.

Hi,

I RANDOMLY get the same error. I posted all the apport-collect out put above. There are several related bugs (maybe identical) and threads listed here (some of them):

http://ubuntuforums.org/showthread.php?t=1145034
http://ubuntuforums.org/showthread.php?t=965935

(and many others)

Here is a summary of what I found out:

1- This bug appears to be kind of RANDOMLY happening. After a fresh install, I used to get this shutdown crash. For a couple of days it went away. But then it again came back. I did install some packages in between (totally unrelated to wireless: acroread etc.)

2- Usually (not always) when I shutdown/restart the machine on battery, everything seems to be OK. No kernel panic, no iwlagn error. nothing.

3- It seems that when I turn off the wireless and then shutdown/restart, everything is OK.

4- Some users have observed that when splash is removed from the menu.lst, the problem doesn't happen. I have also observed that. Although, I didn't permanently remove the splash - I just did it a couple of times using grub editor during boot up, and in all those instances, the shutdown process went smoothly. I don't know if this was just random or not.

5- I couldn't find a version of kernel traceback in /var/log/kern.log or /var/log/kern.log.0 (it seems to be missing from there). However, during shutdown, when I press CTRL+ALT+F7, there is a kernel panic. The last messages before the kernel panic is this (I wrote down from the monitor):

[ 371.328580] iwlagn: Error: Response NULL in 'REPLY_ADD_STA'
[ 371.344681] general protection fault: 0000 [#1] SMP
[ 371.344752] last sysfs file: /sys/devices/pci0000:00/0000:00:1c.2/0000:04:00.0/rfkill/rfkill0/state
[ 371.344831] Dumping ftrace buffer:

The picture of the rest of the traceback is attached. After the traceback, the following messages appear:

* Killing all remaining processes... [fail]
* Deconfiguring network interfaces... [OK]
* Unmounting temporary filesystems... [OK]
* Deactivating swap... [OK]
* Unmounting local filesystem.... [OK]
* Will now halt

And then hangs indefinitely. I can either press and keep power button to turn it off, or I can press CTRL+ALT+DEL to restart the system.

Looking at the kernel panic, it seems that something is wrong with iwlagn.

6- A suggested work-around can be found in this forum:

http://ubuntuforums.org/showpost.php?p=7149271&postcount=22

Some users have reported that this work around fixes their problem. However, this might be just random as well.

[fari81 (fmmirzaei)]

I changed the status to confirmed. If it is still incomplete, please let us know what is needed to complete it.

Thanks.

Guys,

I've installed linux-backports-modules and the problem is fixed now :D.

The system doesn't hang indefinitely when shutting down. Although when I press CTRL+ALT+F7, I still can see the following errors:

iwlagn: Error: Response NULL in 'REPLY_ADD_STA'

or

Killing all remaining processes... [fail]

but I do NOT get a Kernel panic anymore and the system continues to shutdown normally. I've done this about a week ago and since then, I've got no kernel panic and no hangs.

However, this might be just random. Please test it on you systems and report if this also fixes your problems.

Faraz

[Maurizio (maurizio.g)]

although I updated the kernel at the same time, installing linux-backports
fixes for me as well :)

All I did was install the updates which updated the kernel to:

 2.6.28-13-generic #44-Ubuntu SMP Tue Jun 2 07:55:09 UTC 2009 x86_64 GNU/Linux

The issues is now resolved for me through five test shutdowns

[Charles Profitt (cprofitt)]

The previous report was inaccurate... when I went to shut down the computer for the 6th time it hung gain. Since that hang I have not had a successful shutdown w/o first running the command:

sudo ifconfig wlan0 down

[fari81 (fmmirzaei)]

Charles,

Have you tried installing linux-backports-modules?

Since I installed that, I don't have this problem anymore (even after kernel update).

[ndee (ndee-gmx)]

Hi,

issue still persists for me with Linux ndee-tp 2.6.28-13-generic #44-Ubuntu SMP Tue Jun 2 07:55:09 UTC 2009 x86_64 GNU/Linux

[Kamil Páral (kamil.paral)]

Same problem with Thinkpad R61. I attach a stack trace.

[António Lima (amrlima)]

linux-backports-modules solved the problem for me. tested more then 10 reboots and a couple of shutdowns.

[ndee (ndee-gmx)]

Hi,

don't get me wrong. But why isn't this issue patched on the current stable release. I am sure there are thousands of people out there who are angry because their Ubuntu does not shutdown properly. I wonder why the "userfriendliest linux approach" is of no importance here. Sorry but Ubuntu claims to be easy to use and instead of solving the issue with an update people should find docs and hack their system to get backports? Something is wrong in Ubuntus strategy.

I installed Ubuntu on my R61 because I had no time to compile Gentoo, I regret it already ;-)

[Lorenzo Pompili (lorenzo-pompili)]

Solution (for me)
apt-get install apmd
gedit /etc/modules
add this line===> apm power_off=1

cheers

ifconfig wlan0 down

works for me on my laptop.

For those who use Kubuntu (KDE 4+) and dont wan't to type that command on each halt/reboot, here's what I've done :

create 2 scripts which are executable by root. One for halt, on for reboot.

basically the script are

#!/bin/sh
ifconfig wlan0 down
halt

and

#!/bin/sh
ifconfig wlan0 down
reboot

Then, in the "Lgin Manager" configuration,

change the commands to run from

/sbin/halt to yourhaltscript

and

/sbin/reboot to your rebootscript.

This way you'll enjoy a normal user experience.

(but I don't know wht will happen if you use networked filesystems and so on, guess it's safe but ain't sure).

[wiz21 (schampailler)]

oops in my previous msg, one shoud read /sbin/halt(reboot) instead of halt(reboot)

For those who suffer from that bug, here is workaround script that you can put in /etc/rc0.d/ and /etc/rc6.d/ with execution permission (sudo chmod +x /etc/rc0.d/K00killwlan) in order to shutdown and restart properly.

[Simon Déziel (sdeziel)]

With Jaunty on a Thinkpad SL400, when I shutdown my system hang with the following messages :

nm-system-settings: SCPlugin-Ifupdown: device removed (uid: /org/freedesktop/Hal/devices/net_00_23_xx_xx_xx_xx)
nm-system-settings: Ifupdown: get unmanaged devices count: 0
nm-system-settings: SCPlugin-Ifupdown: device removed (uid: /org/freedesktop/Hal/devices/net_00_21_xx_xx_xx_xx)

When I press Ctrl-Alt-F7 I have this :
* Asking all remaining process to terminate... [ OK ]
* Killing all remaining process... [ OK ]
* Deconfiguring network interfaces...

If I turn off my wireless card *at this point* I get this :

[ xxxx.xxxxxx] iwlagn: Radio Frequency Kill Switch is On:
[ xxxx.xxxxxx] Kill Switch myst be turned off for wireless networking to work.
[ xxxx.xxxxxx] iwlagn: Error sending REPLY_STATISTICS_CMD: enqueue_hcmd failed: -5

I can still reboot properly with SysRq but it's a bit annoying.

The only way to shutdown/reboot properly is to turn off wireless before.

Installing linux-backports-modules-jaunty fixes the issue but I still believe it would be nice to fix this without
this "hack".

This bug also affects me : If I disable my wireless card, my computer can shutdown properly. If my wifi card is enabled, the computer hangs at the end of the shutdown process. I just have a black screen and nothing happens.

I am on Jaunty 2.6.28-15-generic #49-Ubuntu SMP Tue Aug 18 19:25:34 UTC 2009 x86_64 GNU/Linux

My laptop is a Dell XPS 1530.

Wifi card : Network controller: Intel Corporation PRO/Wireless 4965 AG or AGN [Kedron] Network Connection (rev 61)

I also have a friend which called me to ask why his computer cannot shutdown (I have installed Jaunty on it). He is not a geek and I had to explain him by phone that he had to remove the battery to shutdown his computer (holding the power button did not worked).

What can I do to help this bug to be fixed ? This is a very important issue.

[Simon Déziel (sdeziel)]

Hi ktulu77,

An easy workaround is to turn off the wireless card before shutdown. You can do that using the hardware switch on the laptop or using the software switch (right click on the Network Manager icon near the date).

The other solution would be to install the package linux-backports-modules-jaunty. To do that you need to enable the backport repository. Open a terminal and copy-paste the following command :

echo "deb http://archive.ubuntu.com/ubuntu jaunty-backports main universe multiverse restricted" | sudo tee -a /etc/apt/sources.list && sudo apt-get update && sudo apt-get upgrade

[ktulu77 (ktulu-highwaytoacdc)]

Ok thank you. I will explain that to my friend.

I have switched to Karmic alpha6 on my laptop and all is ok, It can shutdown correctly.

Thank you very much for your confirmation and for keeping the bug report updated. Since you are the reporter of this bug, that means that the bug is fixed in karmic.

The K00killwlan script contributed by Saïvann Carignan worked perfectly, except that I think the name should be S00killwlan.
