8086:4230 iwlagn sometimes doesn't work after suspend/resume

[Pedro Côrte-Real]

On my Lenovo X61 with an intel wireless card sometimes wireless doesn't work after suspend. NetworkManager will try continuously and fail to associate with the AP. daemon.log shows:

Jun 25 16:53:40 nash wpa_supplicant[1349]: Authentication with 00:22:b0:f0:30:f6 timed out.
Jun 25 16:53:40 nash wpa_supplicant[1349]: Failed to initiate AP scan.

After reloading the driver (rmmod iwlagn; modprobe iwlagn) everything works fine again. The bug triggers very seldomly. Maybe 1 in 100 suspend/resume cycles, maybe less, so it's hard to test against newer kernels.

Hi Pedro,

If you could also please test the latest upstream kernel available 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. Please let us know your results.

Thanks in advance.

I tried it with linux-image-2.6.34-02063401-generic and couldn't trigger the bug. Whereas linux-image-2.6.32-23-generic seems to suffer from it very often.

[Jeremy Foshee (jeremyfoshee)]

This bug report was marked as Incomplete and has not had any updated comments for quite some time. As a result this bug is being closed. Please reopen if this is still an issue in the current Ubuntu development release http://cdimage.ubuntu.com/daily-live/current/ . Also, please be sure to provide any requested information that may have been missing. To reopen the bug, click on the current status under the Status column and change the status back to "New". Thanks.

[Pedro Côrte-Real (pedrocr)]

I have done the upstream kernel test and removed the needs-upstream-testing tag as requested, is there anything else that was required?

[penalvch (penalvch)]

Pedro Côrte-Real, 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? Can you try 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 run the following command in the development release from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

Also, if you could test the latest upstream kernel available that would be great. 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.
