I have a quad socket octo-core system running FreeBSD. Currently, I need to turn off HyperThreading to get it to boot, as FreeBSD only supports 32 CPUs. There were some patches made awhile ago against a trunk version of 8.1, but even after modifying them slightly to work and compile with 8.1-RELEASE, the machine wouldn't boot.
Has there been any progress here? I can't find much good information about it, Google thinks I'm talking about 64-bit architecture and not literally 64 CPUs.
