Description of problem: On a single-processor Opteron 246 system, x86info fails with the message "readEntry: Operation not permitted", then "found 1 CPU" (with no newline). Same results with any arguments, including "-a" and "-h". Version-Release number of selected component (if applicable): x86info-1.15-1.11 How reproducible: 100% Steps to Reproduce: 1. run "x86info -a" (or other args) Actual results: [root@bang ~]# /usr/sbin/x86info -a x86info v1.15.

I can provide an account for SSH access to the Opteron system exhibiting the failure, if that is useful to you.
1.16 is in updates, and that should fix this.
