Hi,

I built PAPI 4.1.3.0 (from a recent UTK CVS snapshot) and enabled libpfm4.
I had a small problem building it (I will send a separate email with a
patch that fixed the problem).

I installed it on a Nehalem system and ran papi_native_avail.  It finished
like this:

  400003e1   :sys_enter_splice  | sys_enter_splice
|
  400003e2   :sys_exit_splice  | sys_exit_splice
|
  400003e3   :sys_enter_tee  | sys_enter_tee
|
  400003e4   :sys_exit_tee  | sys_exit_tee
|
  400003e5   :sys_enter_setxattr  | sys_enter_setxattr
|
  400003e6   :sys_exit_setxattr  | sys_exit_setxattr
|
TOO MANY NATIVE EVENTS

It is neat to see kernel events in this list but this is probably not how
it should have finished.

Is this result unique to my build or have others seen the same results ??

Thanks
Gary
