redhat detecting too many cpus?

[Michael Scully]

Are these Dual Core Xeon Processors?  The DC chips look like two separate
processors, since they essentially are.  They just happen to be on the same
package.

It seems that your machine is HT-enabled. Check this out:

Would you like a precise information, you should check with your vendor.
