A first control hub component, within a computer system, having a first logic to synchronize an internal clock generator of the first control hub with an external clock generator in response to the external clock generator transitioning to a high power state. In response to the internal clock generator being synchronized with the external clock generator, the first logic initiates the first control hub to transmit a request packet to a second control hub via an interface. The first logic monitors the interface for receipt of a completion packet in reply to the request packet, wherein in response to the completion packet the first control hub is operable to continue communication with the second hub via the interface.
