On wakeup from the D3cold full HECI link reset is required. The driver should detect that firmware requests link reset and initiate the link reset flow. In the usual flow the connect IOCTL will trigger the wake from D3cold and corresponding link reset. The MEI driver invalidates all open handles on link reset including the one that triggered the wake rendering this connection unusable. To break this loop make connect detect that it is interrupted by link reset and retry connect attempt after reset was completed.
