Title: Wrong number of processors reported
Post by: junrau on March 27, 2013, 05:20:34 AM

My SME 8 is running on an Intel Pentium D 940 (dual 3.2GHz) and Intel D945Pvs motherboard.  The kernel is 2.6.18-348.3.1.el5PAE (SMP), and yum install says that is the latest.

/proc/cpuinfo shows only 1 CPU.  The previous hardware (last week) was a Core 2 Xeon 1.6 GHz, and 2 CPUs were reported correctly.

Any ideas on why the current processor isn't showing as 2 processors?

Is there a bios setting to enable/disable the second core &/or hyperthreading?

Yes, and it has always been on.

What happens if you turn it off?

try this:

Code: [Select]

cd /boot
mv initrd-`uname -r`.img initrd-`uname -r`.img.old
mkinitrd initrd-`uname -r`.img `uname -r`

and reboot

It still reports 1 processor.

I will try toggling the BIOS setting for multiple cores when I have a chance.

try this:

I'm curious as to why you suggested that Stafano. AFAIK, CPU detection is entirely a function of the kernel, and not affected at all by anything in the initial ramdisk.

I would suggest that OP boots CentOS 5 and follows up with the M/B manufactorer and/or CentOS forums. IMO this is very unlikely to be anything SME server specific.

I toggled single processor mode in the BIOS and there was no change.
