Hi, Jeff.
I have such mismatch. This is an Intel E7200.
FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs
FreeBSD/SMP: 1 package(s) x 1 core(s) x 2 HTT threads
cpu0 (BSP): APIC ID: 0
cpu1 (AP/HT): APIC ID: 1
So it should be instead: 1 package(s) x 2 core(s)
cpu0 (BSP): APIC ID: 0
cpu1 (AP): APIC ID: 1
kern.sched.topology_spec: <groups>
<group level="1" cache-level="0">
<cpu count="2" mask="0x3">0, 1</cpu>
<flags></flags>
<children>
<group level="3" cache-level="1">
<cpu count="2" mask="0x3">0, 1</cpu>
<flags><flag name="HTT">HTT group</flag>
</flags>
</group>
</children>
</group>
</groups>
