Description of problem:
The Intel SE7501WV motherboard supports SMP, while the dmesg should that "SMP
motherboard not detected.". 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):
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
generally this is a bios problem, but could you attach the full dmesg for
Created attachment 93576 [details]
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.
