Systems and methods for maintaining an order of transactions in the coherence point. The coherence point stores attributes associated with received transactions in an input request queue (IRQ). When a new transaction is received with a device ordered attribute, the IRQ is searched for other entries with the same flow ID as the new transaction. If one or more matches are found, the new transaction entry points to the entry for the most recently received transaction with the same flow ID. The new transaction is prevented from exiting the coherence point until the transaction it points to has been sent to its destination.
