Yes, the valgrind issue is a bummer, but we'll get that fixed in the downstream
distributions with a new valgrind version. If you are using bleeding edge glibc
you may also sometimes need the most recent developer tooling to understand
what it's doing :-}

I would also hope that all of our users are happy to have hardware enablement
early before hardware is available to consumers :-)
