Jasper, the next step is to fully reverse commit bisect from kernel 3.16 to 3.19-rc2 in order to identify the last bad commit, followed immediately by the first good one. Once this commit has been identified, then it may be reviewed as a candidate for backporting into your release. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F ? Please note, finding adjacent kernel versions is not fully commit bisecting.

Hypothesus: This is a bug related to upgrading the kernel. What I have done: Using apt-btrfs-snapshots I reverted until I found the upgrade that caused the problem. No X, or X related components were updated on this boundary. Changing the booted kernel did show the problem. Kernels tried that worked: vmlinuz-3.16.0-23-generic vmlinuz-3.16.0-24-generic vmlinuz-3.16.0-25-generic Assuming that 'ubuntu-bug linux' has included enough information.
