Solitaire, if the issue is not reproducible in mainline (which the Utopic kernel is rebased off of) but is in Proposed, then it would appear a downstream (Ubuntu) issue, not an upstream one. Hence, I'll mark this Triaged for now as bisecting the downstream Ubuntu kernel to a specific commit tends to end in a merge base issue noted in https://wiki.ubuntu.com/Kernel/KernelBisection .

Thank you for your understanding.
