            Description

            In some specific timing cases, the device protocol implementation might generate a "PNS_IO_EVENT_PROVIDER_UPDATE_REQUIRED" event before the corresponding work lists in the RTC scheduler have been activated. When an application immediately performs the requested exchange, the scheduler might be using old working lists not performing the expected actions resulting in a race condition blocking futher actions.

            It is expected, that the "PNS_IO_EVENT_PROVIDER_UPDATE_REQUIRED" event is delayed until the scheduler has activated the most recent working list.
