Londé Ngosso, the next step is to fully reverse commit bisect from
kernel 4.5-rc2 to 4.5-rc3 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.
