; 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: CYC packet dropped
