Ian Booth, the next step is to fully reverse commit bisect from kernel
4.3 to 4.4 in order to identify the last bad commit, followed
immediately by the first good one. Once this good commit has been
identified, it may be reviewed for backporting. 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.

After the fix commit (not kernel version) has been identified, then
please mark this report Status Confirmed.

Thank you for your understanding.
