Not normal.

That's normal because there is already a description registered.

In perfmon_intel_core.c, look at the :
static int pfm_core_probe_pmu(void)
{
unsigned int i;
/*
* Check for Intel Core processor explicitely

if (cpu_data->x86 != 6 || cpu_data->x86_model != 15)
If you come in with 6,14, this should fail. But it seems you have things
compiled in, so maybe there is something wrong there
