From: John Harrison <John.C.Harrison@xxxxxxxxx> The previous update to enable the workaround on ARL only changed two out of three places where the w/a needs to be enabled. That meant the GuC side was operational but not the KMD side. And as the KMD side is the trigger, it meant the w/a was not actually active. So fix that.
