It seems to be the same problem as I am having with my Dell Latitude E7440 with Ubuntu 14.04.03, Ubuntu 15.04 amd64, Ubuntu 15.10 amd64, and also when testing with the latest upstream kernels.
I raised a separate bug report for the problem as requested by Christopher M. Penalver 22/10/15; this bug report is currently active (https://bugs.launchpad.net/bugs/1513914) I am not sure about the link, it seems to suggest that it has already been fixed in kernel 3.1.6+, but I am now up to kernel 4.4.0 and the problem still exists.
