I have verified the kernel image provided above. The PCR5 values in the TCG logs and in the TPM match. I have also verified that the ExitBootServices event is present in the binary_bios_measurements. However, I see there is a mismatch for PCR4 and PCR7 between the TCG logs and the TPM values. I am not sure if that is expected or is it something to be concerned about.
PCR4 logs the EFI Service Application events. Attaching screenshots of the PCR values and PCR4 log events for your reference. ** Attachment added: "Zip file containing PCR value screenshots from the TCG logs and the TPM" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1838796/+attachment/5306971/+files/PCR-Values.zip -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1838796 Title: TPM event log does not contain events measured after ExitBootServices To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1838796/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
