Ok, latest update on building an smp rtai kernel. Using the 2.6.24.7 kernel at kernel.org, and following the basic instructions for building a kernel on Debian Lenny (http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Debian_Lenny_Compile_RTAI) I found that there was a package missing from those instructions, specifically zlib. I installed zlib1g-dev and everything compiled properly.
First I compiled with none of the rtai modifications and used the defaults in menuconfig. That successfully built a kernel, which when installed and booted correctly showed 4 processors with cat /proc/cpuinfo. It selected by default the PentiumPro for the processor family. I used the same selection when building the rtai kernel but otherwise followed the Debian Lenny instructions. Specifically SMP is enabled. When I build, install and boot from that kernel, cat proc/cpuinfo now shows only a single processor. Anyone have an idea what in the rtai build instructions is turning off the detection of additional processors?
