Comment 17 for bug 789508

Would it be possible for you to test the latest upstream kernel? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . If possible, please test the latest release candidate kernel (Not a kernel in the daily directory). Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag(Only that one tag, please leave the others). 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.

If this bug is fixed by the mainline kernel, please add the following tag 'kernel-fixed-upstream-KERNEL-VERSION'. For example, if kernel version 3.1-rc9 fixed and issue, the tag would be: 'kernel-fixed-upstream-v3.1-rc9'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

There are newer 3.2 kernel packages for precise available here: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.2.30-precise and 3.5 kernels here:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-quantal/

Also, it would be interesting if you could test the latest Ubuntu Quantal daily iso image.
Thanks in advance.
