title: oprofile 0.9.8 failing under Ubuntu 12.10 with Pentium D
body: <p>I am trying to use oprofile 0.9.8 under Ubuntu 12.10 running on a Pentium D processor (Dell OptiPlex-GX620 desktop). When I try something simple like "operf ls" I get</p>
  
  <pre><code>perf_event_open failed with Invalid argument
  Caught runtime_error: Internal Error.  Perf event setup failed.
  Error running profiler
  </code></pre>
  
  <p>I have success running oprofile in legacy mode using opcontrol commands under sudo by installing the module with timer=1 (see below).</p>
  
  <p>It appears that operf is unhappy in this configuration - which is the new preferred method.</p>
  
  <p>I have verified that all the dependent packages are loaded.</p>
  
  <p>On the oprofile website they do not call out pentium D as a seperate architucture so not sure if it is using regular Pentium architecture.</p>
  
  <p>I have searched everywhere and can't find anything like this reported. Any help would be appreciated in identifying the problem here.</p>
  
  <p>P.S. When I run with legacy mode using opcontrol I have some success:</p>
