["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

lorenzo.chianura, the next step is to fully reverse commit bisect from
kernel 4.2 to 4.3-rc7 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.

Thank you for your understanding.
