Hi bluppfisk, Can you help to provide the following information:
1. upload the /sys/kernel/security/tpm0/binary_bios_measurements, you can cp it into ~/ and then upload it to Launchpad bug as it's in-memory file, so it should be amount of bytes in size. 2. check if TCG event log can be extracted by fwts sudo add-apt-repository ppa:firmware-testing-team/ppa-fwts-stable sudo apt-get update sudo apt-get install fwts sudo fwts tpmevlogdump attach results.log to this bug 3. add loglevel=8 to kernel cmdline or GRUB_CMDLINE_LINUX_DEFAULT to capture dmesg with all levels. Also attach dmesg to this bug I'm verifying various devices with TPM2 on ubuntu core and ubuntu 20.04 so maybe I can try to help for cross reference. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1901312 Title: tpm module malfunctions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1901312/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
