b44 Broadcom Ethernet stops working after installation of backports modules

[Anton Kraus]

Binary package hint: linux-backports-modules-2.6.27-7-generic

My onboard ethernet works fine with the latest kernel.
With the backports modules installed, however, this isn't the case.

lspci tells the following:
02:05.0 Ethernet controller: Broadcom Corporation BCM4401 100Base-T (rev 01)

dmesg shows several error messages about the b44 module:

I hope this information helps.

I have the same issue, with my dell. dmesg shows me the same errors when I try to load b44 module.

[Matthias Metzger (macellarius)]

I'm also on a dell ubuntu notebook and I'm experiencing exactly the same problem. b44 module does not load in kernel 2.6.27-7.
It's the same as in bug #251538.

[Chris Coulson (chrisccoulson)]

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't fix it without more information.

Please include the following additional information, if you have not already done so (pay attention to lspci's additional options), as required by the Ubuntu Kernel Team:
1. Please include the output of the command "uname -a" in your next response. It should be one, long line of text which includes the exact kernel version you're running, as well as the CPU architecture.
2. Please run the command "dmesg > dmesg.log" after a fresh boot and attach the resulting file "dmesg.log" to this bug report.
3. Please run the command "sudo lspci -vvnn > lspci-vvnn.log" and attach the resulting file "lspci-vvnn.log" to this bug report.
4. Please run "modinfo b44" and paste the output.

For your reference, the full description of procedures for kernel-related bug reports is available at https://wiki.ubuntu.com/KernelTeamBugPolicies Thanks in advance!

Ok, "uname -a" : 2.6.27-7-generic #1 SMP Thu Oct 30 04:18:38 UTC 2008 i686 GNU/Linux

linux-backports-modules-2.6.27 (2.6.27-7.5) intrepid-proposed; urgency=low

  [Tim Gardner]

  * Fix search for iwl5000 firmware file name.
  * Update compat-wireless to wireless-testing master-2008-10-31
  * reverted wireless-testing "ath5k: Update interrupt masking code"
    which causes problems with ath5k.

 -- Tim Gardner < <email address hidden>> Mon, 03 Nov 2008 10:58:09 -0700

Even though the changelog doesn't mention b44, the change is actually buried in the 'Update compat-wireless' part.

[Matthias Metzger (macellarius)]

hm, for me the updated package doesn't work. same behaviour as before.

[Anton Kraus (done)]

I can confirm that the problem persists with the proposed update.

[Matthias Metzger (macellarius)]

problem persists even in the updated version

[Tim Gardner (timg-tpi)]

linux-backports-modules-2.6.27 (2.6.27-7.6) intrepid-proposed; urgency=low

  [Tim Gardner]

  * Really update to wireless-testing master-2008-10-31
    Somehow either git failed me, or it was pilot error,
    but the last upload wasn't master-2008-10-31. This also
    includes the b44 driver.
    -LP: #293217

[Matthias Metzger (macellarius)]

The problem still persists with the update. Can anyone confirm this behaviour?

sudo modprobe b44 gives this output:
FATAL: Error inserting b44 (/lib/modules/2.6.27-7-generic/kernel/drivers/net/b44.ko): Unknown symbol in module, or unknown parameter (see dmesg)

[Matthias Metzger (macellarius)]

ok, sorry. now it's working.

[Anton Kraus (done)]

The second fix works.

Thank you very much :)

[Greg (greg-thesantosfamily)]

Mine is still broken on 2.6.27-7.

Do I have to go back to 2.6.27-7.6 from 2.6.27-7-generic?

Can you tell me how to correct this?

[Michael Croteau (michael-fd-croteau)]

I'm new to Ubuntu so I ask for your patience in advance please.

While running Hardy I compiled Madwifi and had success with Atheros chipset and Broadcom wired connect. I did a clean/fresh install of Intrepid and after installing linux-backports-modules-intrepid to enable my Atheros wifi card AR5007Eg I succeeded in getting wifi but lost wired network.

See below for results of:
1. $ uname -a
2. $ modinfo b44
3. ** dmesg.log attached separately
4. ** lspci-vvnn.log attached separately

I can provide any further information required but I am hoping someone can help me to get my wired connection back.
Thank you.

Further to my previous post I add another attachment.

@Michael - subscribe to the proposed pocket, then update again.

System->Administration->Synaptic Package Manager->Settings->Repositories->Updates

[Michael Croteau (michael-fd-croteau)]

Thanks for the help Tim - it works beautifully!

I had mistakenly subscribed to intrepid-backports instead of intrepid-proposed!

Thank you very much!!
