I just built a new box with Debian, and hoit a snag I can't figure out how to get around. The processor in the computer is an AMD X2 4200. All the live CDs I tried (Knoppix, Kubuntu and Gentoo) saw the dual nature of this guy, and cat /proc/cpuinfo showed processors 0 and 1. The default install of debian testing with a 2.6.15.1 kernel shows only one processor. I am very unfamiliar with this. Is it modules, software, or something else that allows Debian to see the processor as dual core, and register it as 2 processors?

you probably need support for SMP. check 'zcat /proc/config.gz | grep -i smp', 'grep -i smp /usr/src/linux/.config'. those are what i would start looking in in my system.

debian probably have a seperate smp kernel try searching with apt-cache or aptitude.

Thanks guys, you both were correct. The default amd-generic kernel has no support for smp, as told by zcat /proc/config.gz, and apt-cache search 2.6.17-1 smp found both the smp kernel image and headers. Debian doesn't install the kernel source by default, so I couldn't check /usr/src/linux/.config.

In any case, all is good now, and cat /proc/cpuinfo shows processors 0 and 1. Thanks again!
