I guess I just don't see why for non-Intel non-HTT systems what this information provides that already isn't printed out. The dmesg I posted shows four APIC ID's. Other than my electric company no one (people or FreeBSD SW) should care that I have dual-core CPU's. If this information doesn't provide any additional information to the viewer, we shouldn't clutter up dmesg further. On Intel HTT systems, the output could in fact be useful. Not having access to a dual-core HTT Intel system right now, I'm not qualified to say. -- -- David (obrien@FreeBSD.org)
