I manage to avoid doing partnership returns but the 165 instructions say, 

For assets placed in service in taxable years beginning after
December 31, 2016, enter the total amount of depreciation
allowable pursuant to IRC § 167(a) for the taxable year
calculated as if the bonus depreciation had been the full amount
of federal bonus depreciation pursuant to IRC § 168(k).

Is there a long way around the barn here, that says some bonus depreciaton is not allowed?
