Bonding Mode 6 (balance-alb) Causes Kernel Oops

[Caleb Anthony]

When configuring ethernet bonding on Ubuntu 10.04.1 - 2.6.32-25-server #45-Ubuntu SMP Sat Oct 16 20:06:58 UTC 2010 x86_64 GNU/Linux, setting mode 6 (balance-alb) causes a kernel Oops once some network traffic is sent or recieved on the interface.

The problem is with the bonding kernel module. I believe that this issue has been resolved in 2.6.35 with the following commit:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=d8190dff018ffe932d17cae047c6b3d1c5fc7574

Here is my /etc/network/interfaces to reproduce the problem:

auto bond0
iface bond0 inet dhcp
        slaves eth0 eth1
        bond-mode 0
        bond-miimon 100
        bond-primary eth0 eth1

auto bond1
iface bond1 inet static
        address 192.168.0.1
        netmask 255.255.255.0
        slaves eth2 eth3 eth4
        bond-mode 6
        bond-miimon 100
        bond-primary eth2 eth3 eth4

Hi Caleb,

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 670547

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.
