Sorry, I have zero TPM programming experience; I've only checked the TCG
specs for responding earlier...

I suggest adding DEBUG macro invocations all around the problematic code
path, and narrowing down the issue as much as possible. You might want
to test on a different TPM chip as well (different physical board, or
maybe try swtpm with QEMU / OVMF).
