Bug still persistent with 4.10.0-041000-generic

Benny, to confirm a regression, if you boot into a Ubuntu 14.10 kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.16.7-utopic/ is this still reproducible?

My Laptop with this running Ubuntu is of great importance right now (school) :-), I will check on that after school is over (June)
