Geoff Williams, the next step is to fully commit bisect from kernel 3.13 to 3.16 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.

I was able to boot to a previously installed kernel (3.13.0-44-generic) and the system performs as expected and is stable. - - Debug info - ========= - The system has been generating a bunch of problem reports too so I've been clicking the submit button. Happy to rovide futher info or try a few experiments to get this resolved. + WORKAROUND: Boot into kernel 3.13.0-44-generic.
