Strangely though the kernel seems to think the system has only one cpu despite it being hyperthreaded: # sysctl -a | grep cpu kern.threads.virtual_cpu: 1 kern.ccpu: 1948 kern.smp.maxcpus: 1 kern.smp.cpus: 1 hw.ncpu: 1 hw.acpi.cpu.cx_supported: C1/0 hw.acpi.cpu.cx_lowest: C1 hw.acpi.cpu.cx_usage: 100.00% machdep.cpu_idle_hlt: 1 # sysctl -a | grep machdep.hlt_logical_cpus (no results) # dmesg | less FreeBSD 5.3-RELEASE #0: Fri Nov 5 04:19:18 UTC 2004 root@harlow.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC Timecounter "i8254" frequency 1193182 Hz quality 0 CPU: Intel(R) Xeon(TM) CPU 2.40GHz (2405.47-MHz 686-class CPU) Origin = "GenuineIntel" Id = 0xf25 Stepping = 5 Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,S S,HTT,TM,PBE> Hyperthreading: 2 logical CPUs I'll try disabling ACPI if I have to reboot the server once more. >You'll need to get a debug kernel and produce a traceback for us to have >any chance of doing anything for you.
