@Tyler I've tested your kernel on a Dell Edge Gateway 3000 which was showing the same TPM selftest log messages as originally described in this bug. When cold-booted with your kernel I only see the following messages now:
14:57:44 [0.000000] ACPI: TPM2 0x0000000076D537C8 000034 (v03 Tpm2Tabl 00000001 AMI 00000000) 14:57:44 [2.703384] tpm_tis MSFT0101:00: 2.0 TPM (device-id 0xFE, rev-id 4) 14:57:44 [2.714914] tpm tpm0: A TPM error (2314) occurred attempting the self test I was able to verify that the TPM is operational by running the following tpm2-tools commands: $ sudo tpm2_startup -T device --clear $ tpm2_nvlist (produces valid output) Note - in this case, the system is using the in-kernel resource manager, which it appears doesn't initialize the TPM, hence the need for using tpm2_startup to initialize the TPM. The version of tpm2-tools used is 2.1.0. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1762672 Title: TPM on Dell XPS 13 stopped working after upgrade to 18.04 Status in linux package in Ubuntu: Fix Released Status in linux source package in Bionic: In Progress Bug description: [ 0.801334] tpm_tis MSFT0101:00: 2.0 TPM (device-id 0xFE, rev-id 4) [ 0.812132] tpm tpm0: A TPM error (2314) occurred continue selftest [ 0.843629] tpm tpm0: A TPM error (2314) occurred continue selftest [ 0.895424] tpm tpm0: A TPM error (2314) occurred continue selftest [ 0.987230] tpm tpm0: A TPM error (2314) occurred continue selftest [ 1.159026] tpm tpm0: A TPM error (2314) occurred continue selftest [ 1.490819] tpm tpm0: A TPM error (2314) occurred continue selftest [ 2.142530] tpm tpm0: A TPM error (2314) occurred continue selftest [ 3.423100] tpm tpm0: TPM self test failed [ 3.456304] ima: No TPM chip found, activating TPM-bypass!
