Hi Chris,

There are few observations we made while testing.

1. On baseline Ubuntu, we see a PCR7 mismatch. Could you please confirm
if this is a known issue and what is the reason for this mismatch?

2. We were able to validate that there were duplicate entries in the TCG
logs with the test kernel and extending those entries in the PCR matched
the TCG log PCR values. But the same is not true for the baseline
Ubuntu, we did not see duplicate values in the baseline Ubuntu
measurements. Does the test kernel try to fix the PCR7 mismatch too and
also introduces a regression because of duplicate entries?

3. We also noticed that there are no bios measurements exposed by the
kernel when secure boot is turned off. Is it possible to get bios
measurements in that scenario, indicating that secure boot is turned
off?
