gentoo-kernel fails to apply the configuration. In the logs the next message appears: unpack kernel-x86_64-fedora.config.5.13.9: file format not recognized. Ignoring. Other symptoms are that if I use savedconfig or confid.d directory to try to enable I2C_HID_ACPI the generated kernel have that setting disabled (and many others). In fact it seems it doesn't apply any configuration at all. This happens with gentoo-kernel-5.13.15 and 5.13.14 (I didn't tested more) Reproducible: Always

Ignoring. The message from unpack can be safely ignored. That just means unpack did not recognize it as a know archive format, which makes sense because it is a plain text file rather than an archive. As well, I have verified that the fedora config is getting applied. > Other symptoms are that if I use savedconfig or confid.d directory to try to > enable I2C_HID_ACPI the generated kernel have that setting disabled (and > many others). In fact it seems it doesn't apply any configuration at all. I don't know what a "confid.d" directory is. savedconfig definitely works for me. You should probably seek help in a Gentoo support channel.
