Comment 3 for bug 1002920

This fix is included in Ubuntu kernel 3.2.0-25.40, which is currently in precise-proposed. For instructions on how to enable and use -proposed, see https://wiki.ubuntu.com/Testing/EnableProposed

Looking at the names in this bug report I think you'll already know how to use -proposed, but I though it was worth mentioning in case someone else comes across this bug report before the fix is released to -updates.
