To fix this flaw, TPM 2.0 does now not allow the computer to resume after a suspend, and forces a reset instead, unless it had been properly primed dur= ing the suspend. Our TPM kmod does handle this. So, if the computer has a TPM 2.0 installed = and running, one must kldload tpm, otherwise the resume cannot work. It became obvious to me when working myself thru the changelog of OpenBSD, searching for something they do differently: > Identified TPM2.0 devices and performed the 2.0-specific "suspend" > command, allowing the lenovo xlr9 and xlnano using the latest BIOS > (which added S3) to resume." Additionally this hints to something else, too: there is some issue with the S3, which apparently has been deprecated by Intel for the Gen 11 processors, and was later re-added on public demand. But I don't know the details of th= is. --=20 You are receiving this mail because: You are the assignee for the bug.=
