We are using =sys-process/numactl-2.0.2 on ppc64 and amd64 nodes, both with Gentoo and other distros (anyway numactl and libnuma are built Gentoo way from the source code), for quite a long and find it quite stable. Reproducible: Always Steps to Reproduce:
ppc stable
amd64 stable
x86 stable, last arch -> closing.
