Bug Description

On Intrepid 8.10, Wifi (iwl3945) randomly fails to resume after a Suspend to RAM. I'm using the 2.6.27-7 kernel. With Hardy (and kernel 2.6.24), I never had this problem (however the driver produced random kernel panics when suspending the machine).

Unloading and reloading the iwl3945 kernel module doesn't help (I get the same messages in dmesg after re-modprobing it). The only way to fix is rebooting.

dmesg looks like this, after a modprobe:

[37438.188091] iwl3945: Intel(R) PRO/Wireless 3945ABG/BG Network Connection driver for Linux, 1.2.26ks
[37438.188106] iwl3945: Copyright(c) 2003-2008 Intel Corporation

[37438.189771] iwl3945 0000:03:00.0: setting latency timer to 64
[37438.189805] iwl3945: Detected Intel Wireless WiFi Link 3945ABG

[37438.199976] iwl3945: Invalid power index

[37438.204209] iwl3945: probe of 0000:03:00.0 failed with error -5

However, I haven't seen any message from iwl3945 just after a resume whis wifi failure (without manually modprobing the module).

How to reproduce the bug:
1) Suspend
2) Resume
3) Wifi works... or not.

I am getting exactly the same in Intrepid as well.
It used to be more random, now it's more like 9/10 times I resume, the wireless doesn't work until I reboot.
I'm on a Dell XPS M1330 with intel gfx and Ubuntu preinstalled

Hi Guys,

Care to test a few things . . . Can you first try installing "linux-backports-modules-intrepid" to see if it helps. It contains an updated compat-wireless stack. If that doesn't seem to help, care to test and confirm if this issue remains with the most recent pre-release of Jaunty 9.04 (currently Alpha4) - http://cdimage.ubuntu.com/releases/jaunty/ . It contains a newer 2.6.28 based kernel. You should be able to suspend via a LiveCD to try and reproduce. Please let us know your results. Thanks.

I am experiencing a very similar, if not the same, problem. I'm running the latest Jaunty kernel (2.6.28-11-generic). Occasionally, after resuming from suspend-to-ram, my internal iw3945 nic will not respond - the wlan0 device does not exist. The problem persists after removing and re-inserting the iwl3945 module. Here are the relevent messages from dmesg:

[123713.618276] iwl3945: probe of 0000:0c:00.0 failed with error -5

slightly different from what's posted above, but the symptoms are the same. The only way I can figure out to re-enable the wireless is to reboot.

Let me know if there is additional info that can be provided.

Thanks!

I am using vanilla kernel 2.6.28, no problem. But if I use 2.6.29 (and 2.6.29.2), built with old config, the problem occurs as described above.

What confuses me, is that other users with 2.6.28 have the bug, too. I think, that there is some incompatible setting. If you need diffs, send mail to mail at aero2k.de (or write it here, I'll read it).

Care to test and confirm this remains with the latest Karmic 9.10 release? ISO CD images can be found at http://cdimage.ubuntu.com/releases/karmic/ . You should be able to test using a LiveCD. Thanks.

Hi -
I'm running current Karmic 9.10 beta (2.6.31-14-generic), and am experiencing this problem. What's odd is that I had thought this issue had gone away in Jaunty, but upon doing a fresh install of karmic beta, it's back. It seems I have a 50/50 chance of having the iwl3945 come back upon resume. I've compared syslogs of a successful wakeup vs. a failed one, and the difference seems to occur here:

Here is the failed entry:

After I did an apt-get update && apt-get dist-upgrade, which updated the kernel and some other bits, the problem seems to be gone on my computer, I've only came back from sleep three or four times, but it seems now the wifi always return while previously it would fail 100%.

Hi Dhenry,

As main bug reporter, please, can you also confirm that this is not an issue yet? [in 9.10?]

Thanks!

Unfortunately I no longer use suspend to ram, because once I spilled some water on my laptop, and since an hardware problem makes it resume itself randomly :(

So I can't confirm if I still encounter this bug or not.

Hi again,

I can say that with the kernel upgrade the problem is not totally fixed here. It went to 100% of times with no wifi after suspend to maybe 20-30%, but the problem is still there.

Thanks in advance.

No, with the new kernel tonight the wifi was restored 3 times after sleep, but this morning it didn't return. It seems that this happens when the laptop has been sleeping for some time.

(But this kernel boots pretty fast.)

I don't know what it does, but it seems to work. Suspend and resume works now as expected. Maybe this is useful for

Same issue if booting with the hardware switch in the 'off' position, or toggling the wifi kill switch to 'off' then back to 'on'.

I can reliably re-awaken the card with the following command:
$ echo 1 | sudo tee `find /sys/devices -name state | grep ieee80211`

Seems that the killswitch state doesn't transition back to 'on' properly?

I've (completely hopefully) solved the problem installing the latest linux-backports-modules-compat-wireless-2.6.36-2.6.32-27-generic.

regards

The problem has come back after a long suspension...

Please forget the last comment: the solution works, the problem has been that the compat-wireless is for linux image 2.6.32-27, and installing the 2.6.32-28 gets automatically loaded another version of the module iwl3945 (i.e 1.2.26ks). The properly working (in my laptop) version of iwl3945 is the one for wich the command

modinfo -F version iwl3945

results in

in-tree:s

and NOT

1.2.26ks

(so the one coming with the backports and not with the kernel image).

Hi Giancarlo, I'm running Ubuntu 11.10 on Vaio FZ21E. The module is the same (IWL3945) and also the WiFi Card (Intel PRO/Wireless 3945ABG).

Looking in Synaptic I' cant find 'linux-backports-modules-compat-wireless-2.6.36-2.6.32-27-generic', but only 'linux-backports-modules-headers-oneiric-generic'....

Anyway the command 'modinfo -F version iwl3945' gives me 'in-tree:s'..... so I'm not understanding how to solve, the suspend is very much useful for me !!

UPDATE: I workarounded the bug doing as follow:

After suspending, if network comes down, from terminal:

sudo rmmod <your_driver>
sudo modprobe <your_driver>

To view which driver you have give this command: 'sudo lshw -C network'
It should give back something like:

description: Wireless interface
       product: PRO/Wireless 3945ABG [Golan] Network Connection
       vendor: Intel Corporation
       logical name: wlan0
       version: 02
       configuration: broadcast=yes driver=<your_driver> driverversion=2.6.38-8-generic firmware=15.32.2.9 ip=192.168.1.111 latency=0 link=yes multicast=yes wireless=IEEE 802.11abg
       resources: irq:47 memory:edf00000-edf00fff

If doesn't work try this:
Create a file named 'config' in '/etc/pm/config.d/', by giving this: 'sudo gedit /etc/pm/config.d/config'.

Add this line: 'SUSPEND_MODULES="your_driver". Save and reboot.

dhenry, thank you for reporting this and helping make Ubuntu better. Intrepid reached EOL on April 30, 2010.
Please see this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases

We were wondering if this is still an issue in a supported release? If so, could you please provide the information following https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume ? As well, can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ . However, note you can only test Suspend, not Hibernate, when using a LiveCD. If the issue remains, run the following command in the development release from a Terminal (Applications->Accessories->Terminal) as it will automatically gather and attach updated debug information to this report.

apport-collect -p linux <BUGNUMBER>

Additionally, if you could try to reproduce this with the upstream mainline kernel that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.

Please let us know your results. Thanks in advance.

I no longer use ubuntu 8.10. I'm currently running ubuntu 11.04, and haven't seen this issue for a long time. It may even have been fixed in a previous release (ubuntu 9.x or 10.x).
