The ability is actually right there in the Flesh Golem's SRD Entry:
Berserk (Ex): When a flesh golem enters combat, there is a cumulative 1% chance each round that its elemental spirit breaks free and the golem goes berserk. The uncontrolled golem goes on a rampage, attacking the nearest living creature or smashing some object smaller than itself if no creature is within reach, then moving on to spread more destruction. The golem’s creator, if within 60 feet, can try to regain control by speaking firmly and persuasively to the golem, which requires a DC 19 Charisma check. It takes 1 minute of inactivity by the golem to reset the golem’s berserk chance to 0%.
It seems that since Crystal is Intelligent, anyone can use that DC 19 check to control her after she goes Berserk.
