skt.diaz, the next step is to fully commit bisect from kernel 3.16 to
3.19 in order to identify the last good kernel commit, followed
immediately by the first bad one. This will allow for a more expedited
analysis of the root cause of your issue. Could you please do this
following https://wiki.ubuntu.com/Kernel/KernelBisection ?

Please note, finding adjacent kernel versions is not fully commit
bisecting.

Thank you for your understanding.
