Stupid fault, shouldn't continue without core perfmon counter.
```
+		if (!is_intel_chip) {
+			id = raw_cpuid(0x80000001, 0);
+			if (id.c & (1 << 23)) {
+				/* support core perfmon */
+				gp_counter_base = MSR_F15H_PERF_CTR;
+				eax.split.num_counters = 6;
+				num_counters = eax.split.num_counters;
+				report_prefix_push("core perf");
+				check_counters();
+				check_amd_gp_counters_write_width();
+			}
+		}
