Cannot load bridge module: missing symbols

[Alan Robertson]

alanr@ibmlaptop:/var/log$ lsb_release -rd
Description: Ubuntu 12.04.2 LTS
Release: 12.04

Running this kernel after a recent update.
Linux ibmlaptop 3.2.0-41-generic #66-Ubuntu SMP Thu Apr 25 03:27:11 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

After upgrading, kvm can't start my VM that uses bridging. Tracked it down as noted below:

WHAT I DID:
I did a sudo depmod /lib/modules/3.2.0-41-generic/kernel/net/bridge/bridge.ko
              (this appears to succeed - no messages and 0 exit code)
and a $ sudo insmod /lib/modules/3.2.0-41-generic/kernel/net/bridge/bridge.ko

WHAT I EXPECTED:
I expected the bridge module to load.

WHAT I GOT:
insmod: error inserting '/lib/modules/3.2.0-41-generic/kernel/net/bridge/bridge.ko': -1 Unknown symbol in module

Looking at the syslog, I got the unknown symbol messages below:

May 9 17:38:30 ibmlaptop kernel: [ 6162.081081] bridge: Unknown symbol stp_proto_register (err 0)
May 9 17:38:30 ibmlaptop kernel: [ 6162.081143] bridge: Unknown symbol stp_proto_unregister (err 0)
what started me down this path:

WHAT I DID:
Started a virtual machine with bridging enabled using Virtual Machine Manager

WHAT I GOT:
Error starting domain: Cannot get interface MTU on 'br0': No such device
Details:
Error starting domain: Cannot get interface MTU on 'br0': No such device

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 45, in cb_wrapper
    callback(asyncjob, *args, **kwargs)
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 66, in tmpcb
    callback(*args, **kwargs)
  File "/usr/share/virt-manager/virtManager/domain.py", line 1120, in startup

  File "/usr/lib/python2.7/dist-packages/libvirt.py", line 551, in create
    if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self)
libvirtError: Cannot get interface MTU on 'br0': No such device

WHAT I EXPECTED:
For the VM to start like it did before the upgrade.
All the things above came from further investigation of this problem.

Uncertain if this is related, but , there appear to be a lot of broken symbols in this kernel:

Sorry I didn't use ubuntu-bug on this one - but I did on the other bug I just filed - from the same system, the same kernel, the same time frame. See Bug #1178744 all that info should be applicable to this one. I just missed the instruction on running it. Sorry!

[Brad Figg (brad-figg)]

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1178737

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.
