Comment 29 for bug 409233

@pete, @ken -- we need to first confirm whether this is a bug introduced in the Ubuntu delta, as there seems to be almost no mention of this issue elsewhere in the community. Could you test the equivalent mainline kernel to the latest kernel you are seeing this on. You can identify the correct kernel to test at the URL below:

    http://kernel.ubuntu.com/~kernel-ppa/info/kernel-version-map.html

and get the mainline kernel you need from here:

    https://wiki.ubuntu.com/KernelTeam/MainlineBuilds

Please report both versions and the results back here. Thanks!
