Running 4.14-rc6 on Gentoo (also applies to previous kernel versions)

tpm_crb is unable to initiate the fTPM device, giving the following output:
[   22.325150] tpm_crb MSFT0101:00: can't request region for resource
[mem 0xdd869000-0xdd869fff]
[   22.325161] tpm_crb: probe of MSFT0101:00 failed with error -16

Is this a bug in the bios, or a bug in the tpm_crb code? I've attached
output from dmidecode, dmesg and my kernel configuration.

Sincerely,


Gijs Peskens
