I tried your patch and see no regression on Xeon 50xx, 55xx, 54xx. It also improved CPU detection on Xeon 54xx (as well as original Junk-uk's patch). It also improved CPU detection on Xen HVM @ Xeon 55xx @ 3 cores: FreeBSD/SMP: Multiprocessor System Detected: 3 CPUs FreeBSD/SMP: 1 package(s) x 3 core(s) cpu0 (BSP): APIC ID: 0 cpu1 (AP): APIC ID: 2 cpu2 (AP): APIC ID: 4 -- wbr, pluknet
