Hello Woodrow
I think already at steps 1 and 2 something's going wrong: 1. sudo cp /sys/kernel/security/tpm0/binary_bios_measurements ~/temp/ Killed (a 0-byte file now exists with this name in ~/temp/ - I assume it will be of no use to include it here) $ sudo fwts tpmevlogdump Running 1 tests, results appended to results.log Test: Dump Tpm2 Event Log. Killed Tpm2 Event Log. $ cat results.log Results generated by fwts: Version V20.09.00 (2020-09-17 18:08:13). Some of this work - Copyright (c) 1999 - 2020, Intel Corp. All rights reserved.

Some evidence is in: $ sudo cat /sys/kernel/security/tpm0/binary_bios_measurements Killed The device is an XPS 13 9300 (2020 model). I can reproduce the problem on kernels 5.8, 5.9 and 5.9.1 too. Haven't tried any other kernel versions.
