Nik.Th., just to advise, as per https://launchpad.net/ubuntu/+source/linux the Proposed kernel is 3.16.0-26.34 since 2014-11-25. If you have 3.16.0-25-33, then either you didn't setup the Proposed repository correctly, or you have the software pinned so that you aren't pulling down the Proposed version.
