Bug Description
New hardware (AMD Threadripper 2920x with an ASRock X399 Taichi motherboard) and a clean 18.04.1 install. 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-
[ 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.
