Christian, were you having any issues with interrupts? You system was going into this code as well.Unfortunately I'm now unable to test, sorry for the trouble. I replaced my BIOS with UEFI firmware and the problem has disappeared. Please let me know if there is anything else I can do to help.

Just waiting for access to the system again to gather results.
Ok, it looks good. Tested-by: Dan Williams <redacted> Tested-by: Xiaoping Zhou <redacted> It does report: [ 2.546660] tpm_tis IFX0740:00: 2.0 TPM (device-id 0x1B, rev-id 16) [ 2.546823] tpm tpm0: tpm_try_transmit: send(): error -5 [ 2.546824] tpm tpm0: [Firmware Bug]: TPM interrupt not working, polling instead ...at boot, but tpm2_nvlist works ok.
