  * Test that we can successfully enable a probe using a generic event.
- * Currently, all platforms implement 'PAPI_tot_ins' so we'll use that.
+ * Currently, all platforms implement 'cpu_clock' so we'll use that.
  * Note that this test will fail if the system under test does not
  * implement that event.
  *
  * This test will fail if:
- *	1) The system under test does not define the 'PAPI_tot_ins' event.
+ *	1) The system under test does not define the 'cpu_clock' event.
