8086:0084 wifi iwlagn fails to authenticate after wake from suspend

[gds]

Upgraded to 11.10 from 11.04 today. Now when resume from suspend, wifi fails to reconnect saying waiting for authentication. If I use the last kernel from 11.04, 2.4.39 instead of the new 3.0.0, it still works OK. After wake from suspend, if using ethernet it works OK.

Did apport-collect after wifi failure to connect after resume timed out (RED x over wifi icon) and then plugged in ethernet cable.
Just to be clear, suspend == suspend to ram. (Note: suspend to disk has never worked but not relevant to this bug.)

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . If possible, please test the latest release candidate kernel (Not a kernel in the daily directory). Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag(Only that one tag, please leave the others). 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 by the mainline kernel, please add the following tag 'kernel-fixed-upstream-KERNEL-VERSION'. For example, if kernel version 3.1-rc9 fixed and issue, the tag would be: 'kernel-fixed-upstream-v3.1-rc9'.

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

Thanks in advance.

Kernel v3.1-rc10-oneric (latest) doesn't help with this bug.

[Joseph Salisbury (jsalisbury)]

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report at bugzilla.kernel.org [1]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug.

If you are comfortable with opening a bug upstream, It would be great if you can report back the upstream bug number in this bug report. That will allow us to link this bug to the upstream report.

The bugzilla.kernel.org may still be unavailable due to the recent break-in. One alternative would be to report this directly to the subsystem maintainer or to the Linux Kernel Mailing List - <email address hidden>

[1] https://wiki.ubuntu.com/Bugs/Upstream/kernel

[gds (gds-chartertn)]

Yes, bugzilla.kernel.org still offline. So I posted to LKML as you suggest. However, not sure who the subsystem maintainer is so I just posted this message:
https://lkml.org/lkml/2011/10/26/6

[gds (gds-chartertn)]

https://lkml.org/lkml/2011/12/12/294

wwguy on lkml suggests a fix for the problem. I had exactly the same problem with fedora 15 and 16 and it fixes the problem on f16 (which is the only linux OS I am currently running). I suspect this would also fix the problem on Ubuntu also but I am unable to test it at this time.

[penalvch (penalvch)]

gds, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please provide the information following https://wiki.ubuntu.com/DebuggingKernelSuspend ? As well, could you please test for this with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you please 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 <replace-with-bug-number>

Also, could you please test the latest upstream kernel available? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please do not test the kernel in the daily folder, but the one all the way at the bottom. 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. As well, please comment on which kernel version specifically you tested.

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', and comment as to why specifically you were unable to test it.

Please let us know your results. Thanks in advance.

[Cole Markham (markhamc)]

I can confirm the fix suggested by wwguy on lkml fixes the problem on Ubuntu 12.04. The name of the driver has changed from iwlagn to iwlwifi, so that needs to be changed in the modprobe file. To summarize here, I created a file /etc/modprobe.d/iwlwifi.conf with the line:

options iwlwifi bt_coex_active=0

I then rebooted (probably could have unloaded/loaded the module), and wifi reconnects after resuming from suspend.

OR using EOL release, and no response for years.
