[iwl3945] direct probe timeout

[Didier Roche-Tolomelli]

At some start (something like 75% of the time), I can't connect to the network wireless.

Looking at syslog:

So, the only workaround then is to stop network-manager; unload the driver; reload it and restart the nm services.

Please do not hesitate if you need more info.

Thank you for taking the time to file a bug report on this issue.

However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.

We have noted that there is a newer version of the development kernel currently in the release pocket than the one you tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not.

If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released.

Thank you for your help.

[Didier Roche-Tolomelli (didrocks)]

The issue still exists (but less frequently) in latest kernel.

I am experiencing this bug with kernel 3.1.1 and driver iwlagn.

[Jonathan Allard (joallard)]

The issue persists in kernel 3.1.3

Didier Roche, thank you for reporting this and helping make Ubuntu better. 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 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 . 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.

[Jonathan Allard (joallard)]

Please see upstream iwlwifi bug #2346 <http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2346> for more details. More advanced debug information can be found there. Comment #17 on upstream bug says problem persists on kernel 3.3.0.

[Jonathan Allard (joallard)]

I will also move to "confirmed" since several people are experiencing the bug, as per upstream bug report. (<http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2346>)

[penalvch (penalvch)]

Newest kernel available to be tested is 3.4.
