I just built a new server with: Intel SE7501CW2 ServerBoard 2 x Intel Xeon 2.4Ghz 533FSB 2 x 1GB ECC DIMMs Adaptec 2200s RAID (lev 1) FreeBSD 4.10-Beta (cvsup from 4.9-Release to Stable produced this) I built the SMP kernel (I've done this before with older L440GX systems several times with no problems) and everything boots fine (see dmesg below), but ubench shows about half what the performance should be and top only shows 1 CPU running (cpu0). I'm seriously afraid I might have mucked up one of the CPUs when I had to remove and reinstall it, but I would think that I would see some sort of error if that were the case. In the BIOS you see the "system" processor installed, but not the "application" processor installed (not sure if that means the 2nd CPU or not), but both cpu's temperatures are showing up. Here's the relevant boot info: CPU: Intel(R) Xeon(TM) CPU 2.40GHz (2392.04-MHz 686-class CPU) Origin = "GenuineIntel" Id = 0xf29 Stepping = 9 Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,C MOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE> Hyperthreading: 2 logical CPUs real memory = 2146959360 (2096640K bytes) avail memory = 2087825408 (2038892K bytes) Programming 24 pins in IOAPIC #0 IOAPIC #0 intpin 2 -> irq 0 Programming 24 pins in IOAPIC #1 Programming 24 pins in IOAPIC #2 FreeBSD/SMP: Multiprocessor motherboard: 2 CPUs cpu0 (BSP): apic id: 0, version: 0x00050014, at 0xfee00000 cpu1 (AP): apic id: 1, version: 0x00050014, at 0xfee00000 io0 (APIC): apic id: 2, version: 0x00178020, at 0xfec00000 io1 (APIC): apic id: 3, version: 0x00178020, at 0xfec80000 io2 (APIC): apic id: 4, version: 0x00178020, at 0xfec80400 Preloaded elf kernel "kernel" at 0xc0341000.
