With IBM's LTC help, we finally found a Lenovo with the Nuvoton NCPT650.  It's a System x3550 M5[1], not a ThinkStation P320, running Fedora (vmlinuz-4.16.14-300.fc28.x86_64). I replaced the 4.16 kernel with the latest stable 4.19.y kernel.  Both the TPM and IMA seem to be working properly.  Not sure if this helps... >From dmesg: # dmesg | grep -i tpm  [ 0.000000] Linux version 4.19.14 (mimi@x86tpm2Server.rtp.stglabs.i bm.com) (gcc version 8.1.1 20180502 (Red Hat 8.1.1-1) (GCC)) #6 SMP Thu Jan 10 22:32:54 EST 2019 [ 0.000000] efi: ACPI=0x7b786000 ACPI 2.0=0x7b786014 SMBIOS=0x793fe000 TPMEventLog=0x426fa018  [ 0.014413] ACPI: SSDT 0x000000007B784000 0003A7 (v02 INTEL Tpm2Tabl 00001000 INTL 20130328) [ 0.014416] ACPI: TPM2 0x000000007B783000 000034 (v03 INTEL EDK2 00000002 INTL 01000013) [ 2.667052] tpm_tis MSFT0101:00: 2.0 TPM (device-id 0xFE, rev-id 2 # cat /sys/kernel/security/ima/ascii_runtime_measurements | head -2 10 5425744ce804c8cae89a08d53b41ab20ff1b3ea6 ima-sig sha1:7996f7339c3ce64e63f1232ef1aa6033247af784 boot_aggregate I installed the ibmtpm2tss[2], built (eg. autoreconf -i; configure -- enable-hwtpm) and installed it. # export LD_LIBRARY_PATH=/usr/local/lib/ # cd /usr/local/bin # ./tsspcrread -ha 10 -halg sha256 -ns f73ff9109b06d4f7a7cbe7eac32b20d2ca662e55cb4c81e152beea261989ad4b Mimi [1] https://lenovopress.com/lp0599.pdf [2] https://git.code.sf.net/p/ibmtpm20tss/tss
