Hi, for some reasons, I need to install Gentoo on the disk plugged into another machine than what it is intended for ...

Created attachment 99707 [details] .config
FYI: the cross-compiled vanilla kernel (and the whole system) works ok unfortunately I have not enough knowledge to find out which gentoo-specific patch is causing the problem with gentoo-sources
This works fine on a clean gentoo-sources. It does not work when the kernel has already been built for another arch (same as vanilla) because the include/asm symlink points to the wrong arch. Either correct the symlink manually or start from clean sources.

I cannot try since the disk is already in the second machine ... anyway, thankyou for the explanation and sorry for the invalid report - I did not find anything useful about this error on the web, if I knew, I would try make mrproper ...
