Bug Description

The update I just ran that installed initrd.img-2.6.32-29-generic broke wireless on my Lenovo X201 laptop. The apparently relevant messages from /var/log/kern.log are as follows:

I don't have this problem with initrd.img-2.6.32-28-generic, although I have to use backports to get nm-applet to work (see Bug #249404 for that). I'm using that kernel version to type this bug report.

I obviously meant that this bug needed to be reassigned to the linux package, and failed this email update :)

From your comments, I'll also mark this regression-release and let the necessary people know.

Thanks Mathieu. After I noticed the "nm-applet" classification had been picked up from my mentioning that Bug #, I spent about 15 minutes trying to "Link a related branch," but the search widget rejected "linux" and other terms I tried as "too many branches" or something like that.

It seems that the driver is trying to load a version of the firmware which does not exist. A newer version does exist which it is not trying to use. I will note that the maverick firmware does seem to contain both the -4 and -5 versions but lucid does not. That said I am unsure why it suddenly needs it.

Here is version 4 of the microcode. Could you please manually copy it to /lib/firmware and see whether it resolves the problem?

We're going to investigate this further on our end, but knowing whether this resolves it will be helpful.

Thanks!

Yes using that microcode fixed it. Note that my /lib/firmware already contained iwlwifi-6050-5.ucode

Ok thanks for that testing. Could you confirm whether you normally are using linux-backports-modules-wireless for this machine. If so which version. Also could you attach the contents of your /var/log/dpkg.log and the output of the command below:

    dpkg -l | grep ' linux-'

Thanks!

It is also probabal you should be using the linux-backports-modules-wireless-2.6.35-lucid-generic version of this driver as the version in 2.6.32 was not really ready for primetime.

Yes using linux-backports-modules-wireless, specifically synaptic shows linux-backports-modules-wireless 2.6.32-28.27.

You say "you should be using the linux-backports-modules-wireless-2.6.35-lucid-generic version of this driver...." How do I do that?

Walter - you should be using the meta package which will keep your backports package updated, e.g.,

sudo apt-get install linux-backports-modules-wireless-2.6.35-lucid-generic

I removed iwlwifi-6050-4.ucode and the laptop still restarted with no connection issues. So I think the LBM package fixed the problem.
