I'd like to perform a reverse bisect to figure out which commit upstream fixes this regression. It would be very helpful to know the last kernel that had this issue and the first kernel that did not.
Can you test the following kernels and report back: v3.16.7: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.16.7-utopic/ v3.16.7-ckt1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.16.7-ckt1-utopic/ The Ubuntu 3.16.0-26.34 kernel is based off of upstream v3.16.7-ckt1, and the Ubuntu 3.16.0-25.33 kernel is based off of upstream v3.16.7. If v3.16.7 is good and v3.16.7-ckt1 is bad, I can bisect between those two versions.
