After that I could not use `top`, so recompiled the kvm-libs, and then the top-program almost works (it bugs showing wish program that have what pid). But, my computer was WAY slower now then it was before the new kernel, so i think that FreeBSD dont use both my cpu's. I got an AbitBP6-moderboard with 2 celeron 366mhz (unclocked) on. Before i could compile things and use programs at the same time without any problems, now the programs is VERY slow when i do more then one thing at the same time. The kernel find the 2 cpu's in the boot, but i dont think it uses both the cpu's when the system is running. Here is an output from dmesg|grep -i cpu: CPU: Pentium II/Pentium II Xeon/Celeron (367.50-MHz 686-class CPU) cpu0 (BSP): apic id: 0, version: 0x00040011, at 0xfee00000 cpu1 (AP): apic id: 1, version: 0x00040011, at 0xfee00000 SMP: AP CPU #1 Launched! How can i fix so the system is as fast as it was with the original-source when i compiled it for smp, and how do i fix top (and ps)? Why do top and ps bug? I am NOT good at english, and i realy hope you can understand me anyway, if not, please email me and ask becouse i realy want to fix this problems. I can send you my config-file i use when i compile the kernel if you want it. >How-To-Repeat: just cvsup down the latest kernel-source and compile the new kernel. >Fix: None... =( >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
