I purposefully turn on AMD fTPM in the UEFI as I would like to explore using this to secure my system. However after booting with this option no /dev/tpm device node exists and the kernel boot output now includes the following... $ dmesg | grep -i tpm [ 0.000000] ACPI: TPM2 0x000000007902E4D0 000034 (v04 AMD A M I 00000001 AMI 00000000) [ 0.928120] tpm_crb MSFT0101:00: can't request region for resource [mem 0x7943a000-0x7943afff] [ 0.928141] tpm_crb: probe of MSFT0101:00 failed with error -16 [ 1.090180] ima: No TPM chip found, activating TPM-bypass! (rc=-19) I'm using the motherboard vendors latest issued UEFI firmware and am unable to locate any other examples of this issue on my hardware.
