What if you boot with other kernel?

If you have the same result maybe BIOS update is required for your server?!

Hi there,

I'm running an ibm xseries 345/dual Xeon 2.66GHz, 2.6.18-53.1.14.el5xen #1 SMP, and cat /proc/cpuinfo shows me only one processor. Apparently something strange happening with ACPI. What am I doing wrong? Thank you! (sorry for the cross post, didn't realize there was a virt list first time around!)

Selected bits from dmesg:
