Hello,

Per my understanding to the codes, I think the:

* Input parameter 'NamespaceId' for the PassThru() service
* The 'Nsid' field of the EFI_NVM_EXPRESS_COMMAND

are of the same meaning.

Do you think setting these 2 values identical when calling the PassThru()
service can resolve the issue you met?

Best Regards,
Hao Wu
