As the result, it can only able to detect one CPU while my system have two Xeon 2.4 (with HT) CPUs. Version-Release number of selected component (if applicable): kernel-2.4.20-19.9smp How reproducible: Always Steps to Reproduce: 1. boot the machine 2. cat /proc/cpuinfo and it show 1 CPU only 3. dmesg and it should contains "SMP motherboard not detected." Expected Results: 4 CPUs should be shown in /proc/cpuinfo Additional info:
generally this is a bios problem, but could you attach the full dmesg for information?
Created attachment 93576 [details] dmesg
if that is bios problem, is there any suggestion for me to fix this issue? like config/update the bios, or apply patch on the kernel, etc...
there's no sign of any HT being detected at all in your dmesg; I'd suggest looking for a bios upgrade...
the problem was solved once I upgraded the bios.
