The error in question is TPM_RC_TESTING i.e. TPM is still processing selftests in the background. It is clearly a regression but unfortanely it is harmless and unrelated i.e. tpm2_do_selftest() should not print an error message because it is legit behavior. The function actually masks the whole error: if (rc == TPM2_RC_TESTING) rc = TPM2_RC_SUCCESS; /Jarkko
