Yes I have hardware - since March. Everyone should note that difference of dual-core vs. single core doesn't matter one bit for FreeBSD. We don't have NUMA support, which is what is required to care about the difference between 1x dual-core & 2x single-core (or 2x dual-core & 4x single-core) Opteron. For 6.0-RELEASE (which branches June 1, 2005), I'm going to just have the kernel ignore that dual-core Opteron sets the HTT feature flag. -- -- David (obrien@FreeBSD.org)
