Bug Description

When using 2 intel pro/1000 nics that are bonding and adding them to a bridge, My new (entirely updated) jaunty box kernel panics at startup. I get the same error on a Precision 690 as well as an HP DL360 G6.

This worked perfectly in intrepid!!

Actually this happened for me on 8.10, and it happens with broadcom NICs as well. Given this happens on 9.04 as well, and bridged bonds are key to KVM use, this needs to be upped in the priority queue or address sooner than later. VMware implements true layer-2 compliant virtual switches, maybe someone in the KVM community or Ubuntu community should consider this as an option.

Thanks for your report. I changed the package to linux, so that a kernel-developer can see what information he needs from you. For now, please run the command apport-collect -p linux-image-`uname -r` <bug#> , which will include necessary information automatically.

I am seeing the same problem bridging the e1000e ethernet and IWL4965AGN wireless cards on my laptop. This forces me to use NetworkManager, a very suboptimal solution. For me this is an important issue. I am running jaunty, fully updated as of 12/may 2009.

Hi Robstarusa,

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 366179

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.
