[tboot-devel] PCR17 Replay Issue

[Thompson, K. <ken...@in...>]

Hi,
We're encountering an issue in that the event log measurements in PCR17 (see eventlog.json attachment) are not "replaying" with the PCR's final measurement.  In other TXT/TBoot environments, the code that produces the event log and performs replay (of PCR17) are reported to work.  In this case, the environment is...

Bios:  WLYDCRB1.SYS.0020.P35.2101050157
OS: Fedora 34
Tboot: 10.1.2

Does the tboot team have any recommendations on how to investigate this issue?  Is it possible that "startup locality" is in play?

Thanks,
Kent
