Hello, Since Gentoo has an official package for linux-next (https://packages.gentoo.org/packages/sys-kernel/linux-next) the microcode change in linux-next that changed the naming of config options of microcode for amd and intel breaks the build due to them well being missing :) The mentioned change is https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/arch/x86/kernel/cpu/microcode?id=e6bcfdd75d53390a67f67237f4eafc77d9772056 I have fixed it in hacky way locally by editing the microcode options to the new options which resolved the genkernel failure but this is far from a real solution. Cheers :)
