Thank you for your report. The commit you refer to is applied already to the Precise kernel since 3.2.0-25.40. Unfortunately, it looks like the backport of this commit is incorrect and this is probably causing the issue you're hitting.
I've reverted this commit, re-applied it and uploaded a test kernel here:
