Do you know if this issue happened in previous version of Ubuntu, or is this a new issue?

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 v3.2 kernel[1] (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 other tags). 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 3.2-rc1 fixed the issue, the tag would be: 'kernel-fixed-upstream-v3.2-rc1'.

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

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. If you believe this bug does not require upstream testing, please add the tag: 'kernel-upstream-testing-not-needed'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

I'd like to perform a bisect to figure out what commit caused this regression. It would be very helpful to know the earliest kernel where the issue started happening as well as the latest kernel that did not have this issue.

In addition to the latest mainline kernel, would it be possible for you to test the v3.1.0-2.3 kernel? It is available at:
https://launchpad.net/ubuntu/precise/i386/linux-image-3.1.0-2-generic/3.1.0-2.3
