Hi, I'm running Centos 5.1 on an Intel Quad 2 Core with four Q6600 processors. Despite Centos 5 supporting multiple cores (SPM), it doesn't seem to work for me: 1) a dmesg shows that only one processor is seen: "SPM alternatives: switching to UP code", etc. 2) file /proc/cpuinfo shows only one processor 3) top with option 1 (to toggle between seeing all processors or an average) shows only 1 processor.
I've googled this, and other people have found this kind of trouble, but I was not able to find any solutions. By the way: I've installed windows xp to see if it was a bios problem, but windows sees the 4 processors just fine. Any ideas? Thanks, Julian.
