The problem is obvious. Look at your kextcache output. Clearly you have AppleHDA components that are not patched from the native kexts of 10.12... that is, they are from an older version of OS X... and therefore are incompatible.

what about in kextstat | grep -y appleintelcpu -- there is no message there..is it normal?

Normal for Haswell and later.
