It looks like you were right...I copied all the .so files located in /system/lib/ (not the folders) from 221 and copied them to 227. No more FCs. I'll try and narrow it down to a specific file.
Edit: The libaudio.so file is the cause of the FCs. Just replace it with the one from nightly 221
Edit2: This workaround also works with N228
