Bug 170245

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.  Dave Jones 2001-2005

Expected results:
no error, more processor information

The same version of x86info and kernel yields the correct results (and
no error) on an Athlon 64 3500+ system (Asus A8V motherboard), suggesting
that this may be an Opteron-specific bug.
