Thanks for your response! My responses are here: 1) We do have serial logging setup and working. I will work to get the logs off the machine. 2) The platform is TPM2. 3) I am not sure what you mean by this question. Are you referring to index 0x1c10103? (see https://sourceforge.net/p/tboot/mailman/message/35551544/) 4) We are not implementing any launch control policy.

It could be a plethora of things. It would be helpful to have logs from the first phase execution of tboot. Since tboot is generating a hard platform reset you will need serial logging or something else to capture the logs unless you are able to get memory based logging to work. Is the platform TPM1 or TPM2? Given it is i6/i7 I'm assuming the latter. Are the required TPM NVRAM locations configured? Are you attempting to implement any type of launch control policy? Logs and answers to the above questions should help get a conversation started. Have a good evening.
