Pavel, the next step is to fully reverse commit bisect from kernel 4.2
to 4.4.13 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.

Also, the kernel release names are irrelevant for the purposes of
bisecting.

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

Thank you for your help.
