I installed many upstream kernels via UKUU. I did several verifications with shutdown and reboot, last version where both works is 4.6.2, first version where neither shutdown nor reboot works is 4.6.3 . Both kernels 4.5.7 and 4.6 work fine for me.
BTW: Kernel Bugtracker has corresponding bugs (https://bugzilla.kernel.org/show_bug.cgi?id=199349) & (https://bugzilla.kernel.org/show_bug.cgi?id=201965)
