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

Andrey Gadyukov, the next step is to fully reverse commit bisect from
kernel 3.19 to 4.1-rc4 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.
