[iwl] calltrace in driver with "wpa_supplicant Tainted"

not a bug in wpasupplicant

i would suggest that this is a driver problem

thanks for the replies!
any more debug I can add?

Hi BUGabundo,

Is did you see this with or without linux-backports-modules installed?

Hi Leann.
I cant be sure.
I have them installed now, but I'm not sure I had them when I saw that.

Do u need me to retest?

bugabundo, of course. please retest with linux-backport-modules.

Cant reproduce it anymore.
If Thomas confirms that installing linux-backports-modules fixs from him, I think we can close this ticket.

No, I've had the backports installed all along when I got this issue. I cannot reproduce it though, it has only happened once.

I get this something similar when I suspend when I'm connected to a WPA Enterprise network. Were you connected to a WPA enterprise network at the time?

I was either connected to completely unsecured network or not to any at all, can't remember. Absolutely not a WPA enterprise network at least.

I was on wpa entreprise.

this last test was WPA2 psask and none at all... lol

The same thing happened to me again today. It also happens when i modprobe -r iwlagn after it has been connected to a WPA enterprise network.

$modprobe -r iwalgn
segmentation fault

I've attached my kernel log of the event.

This error doest not just occur when I suspend or disable my wifi. I also get the error whenever I try to connect to another network.

Is this bug going to be fixed anytime soon? I have to restart my laptop every time I disconnect from a WPA enterprise network otherwise wifi no longer works. Trying to reload modules results in segfaults and kernel crashes.

timothius did you install linux backports?
For me it fixed the problem

Ah, thanks for that. That fixed the problem :)

I didn't realise that I had to install the backports to fix the issue. I would have thought that it would be released as an update for the current release as it is quite important.

Scrub that. This bug is still present!

Waking for suspend I again got the wpa_supplicant tainted bug. The system had to be restarted yet again..

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.

ok, so backport-modules doesn't fix this issue for timothius

Sorry, but is this bug ever going to be fixed?

I'm not using:

$ uname -r
2.6.27-11-generic

I still get a horrible crash everytime I resume after connecting to a WPA Enterprise network. Please see the log.

Thanks.

I no longer see this on Jaunty.

Timothius could you please test a daily Live CD ?

thanks

Hi,

After the last crash I don't appear to have the issue anymore :) I think i had not rebooted the computer so the updated modules hadn't been used.

I'll keep testing it - but so far far good :)

Thanks

As BUGabundo, the original bug reporter, has commented this is no longer an issue with Jaunty I'm marking this "Fix Released" against the actively developed "linux (Ubuntu)" package. Also seems to be resolved on Intrepid with linux-backports-modules-intrepid, so I'll mark this Fix Released there as well. Thanks.

I'm getting the same issue on Ubuntu 10.04
2.6.32-30-generic

sudo killall wpa_supplicant doesn't work for me

I need to reload the module :
modprobe -r iwlagn
modprobe iwlagn

I'm adding pci information.
If you need more information let me know.
