Per NVM Express Spec, software should notify NVME HW when shutdown occurs. The NVME controller requires notification for shutdown as part of its management of internal structures. Even with FUA, failing to notify the NVME controller to shutdown power off causes the NVME controller to take quite some time to organize its tables on the next power on. This time exceeds the normal timeout, so we would fail to boot the NVME disk. The host should set the Shutdown Notification (CC.SHN) field to 01b to indicate a normal shutdown operation. The controller indicates when shutdown processing is completed by updating the Shutdown Status (CSTS.SHST) field to 10b.
