SSH - OpTee reboot scenario Issue

Hello All,

[please suggest the email list if this is not the right platform to discuss, sorry for that]

We use Op-tee (3.18) in our ARM64 based project (Linux 5.15.14+) for cryption, so basically it is like " OpenSSH -> OpenSSL -> OpTee -> HSM". It works fine until we tried with a test scenario of reboot request via SSH.

When we request the system reboot via SSH, the shutting down looks not a graceful way (ssh client connection exception). This is only we add OpTee layer, otherwise everything works fine. I would like to know anyone has encountered similar kind of issue where OpTee has to take care any special shutting down process. Any leads much appreciated !

Thanks & Regards, Hareesh
