Ilya G. Ryabinkin / Oliver Leitner, the next step is to fully reverse
commit bisect from kernel 4.6 to 4.8-rc4 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.
It is most helpful that after the fix commit (not kernel version) has
been identified, you then mark this report Status Confirmed.
Thank you for your help.
