Gijs, can you provide details, why you think this is a problem in the ebuild and not from upstream? (In reply to Jonas Stein from comment #3) > Gijs, can you provide details, why you think this is a problem in the ebuild > and not from upstream? tbh I'm quite sure it would be either upstream or bios. What upstream bugtracker/mailinglist would be best suited?

Created attachment 487054 [details] kernelconfig The buildin fTPM chip fails to load with following messages in kernel log: gijs@chaotica ~ $ dmesg | grep -i tpm [ 0.000000] ACPI: TPM2 0x00000000DD7963C8 000034 (v03 ALASKA A M I 00000001 AMI 00000000) [ 3.360854] ima: No TPM chip found, activating TPM-bypass!

The processor comes with a firmware based fTPM 'chip'. Enabled it in bios (with all possible permutations of versioning). Compiled kernel with TPM support (unfortunately at this moment there is sparse to no information available on if linux supports the AMD fTPM implementation, and which kernel modules are required) Similar (old) bugs on other motherboards point to a possibility of this being a bios error, also created a ticket at MSI support.
