Kernel v3.16.x, userspace v3.17... is a bit old for this kind of testing. Bugs are still actively being fixed, and before reporting a bug of this sort, updating to see if it's still happening in current (currently v4.0.x kernels and userspace, or even v4.1-rcX kernels and integration-branch userspace), is generally a good idea. -- Duncan - List replies preferred.
