As indicated in my previous reply to Stefan's comment, I have v2 version of the patch which also deals with multiple attempts to start up the TPM gracefully, for example, once by the firmware and another by the kernel during tpm2 auto-startup. If you think the idea is OK, I can send the v2 of the patch. Kind regards Hermin
