Comment 2 for bug 1063670

@Laura -- we need to identify what if any kernel this worked for in 12.04. You should be able to download and install the latest 12.04 kernel and run it against your quantal userspace. You can find those kernels in the version page for the linux package:

If you could try the latest 3.2.x kernel and let us know if that works.
