I have a server with 6.1 and one dual-core processor and the SMP option was built in the kernel according to the doc below, but only zeros show up in the 'C' column of top after I've rebooted with the newly compiled kernel. http://www.freebsddiary.org/smp.php I did not add APIC_IO as the doc suggested as it complains the option is invalid, plus I did not do this for my other 5.4 server which shows all processors in top. Both configs have a device of apic, neither has the APIC_IO option. However, the other server is running 2 physical CPU's and I see 0 thru 3 in the C column in top. Also, dmesg shows CPU #1 Launched along with everything else: esmtp# dmesg|grep CPU CPU: Intel(R) Pentium(R) 4 CPU 3.00GHz (3010.67-MHz 686-class CPU) Logical CPUs per core: 2 FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs cpu0: <ACPI CPU> on acpi0 acpi_throttle0: <ACPI CPU Throttling> on cpu0 cpu1: <ACPI CPU> on acpi0 SMP: AP CPU #1 Launched! Why would I not see any other CPU numbers under top like I do in my other server? -- Robert
