Sven and Tim,

Attached is a one-line fix for the problem that shows up between 3.8.0-36 and 
3.8.0-37. It is just a bare patch file, but feel free to add any explanatory 
text to make it a proper commit.

I have no real understanding as to why this line of code does not cause any 
problems with later kernel versions, but it does here. In addition, I have not 
had any reports of problems with other users. That makes me suspect some kind of 
bad interaction with the user-space network control components in 12.04.

Would it be helpful for Nicolas to prepare a bug report at Ubuntu?

Larry

If you want, I can reinstall Ubuntu 12.04 and update it to the lastest 
Kernel version from Update Manager.
Teach me how to make a Bug Report and I'll send it to you.
(Sorry for my English, maybe your eyes are bleeding)

To file the bug report against the kernel in Ubuntu, open a terminal and
run 'ubuntu-bug linux'. This will guide you through the process of
filing the bug.

Thanks,
Seth

It looks like there is already a bug report in progress for this:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1289429

I'll attach the patch and have Joe build a test kernel.

Tim,

I agree that #1289429 is this bug. It seems that the problem also happens for 
3.5.0-48-generic. If that is being supported, it also needs this patch.

Larry
