+; SKL168: Intel(R) PT CYC Packets Can be Dropped When Immediately Preceding PSB
+;
+; Due to a rare microarchitectural condition, generation of an Intel PT
+; (Processor Trace) PSB (Packet Stream Boundary) packet can cause a
+; single CYC (Cycle Count) packet, possibly along with an associated
+; MTC (Mini Time Counter) packet, to be dropped.
+;
+; Variant: MTC and corresponding CYC packet dropped
