I am surprised there has been so little mention of what happened to the Quantas Airbus A330 and how it could relate to the Air France Airbus A330. The Quantas Airbus had a faulty ADIRU. It has 3 ADIRUs I believe but it failed to listen to the other two and went with the faulty one.

In October 2008 the Qantas Airbus A330-300 was carrying 303 passengers and 10 crew from Singapore to Perth when it experienced what the airline has described as a sudden change in altitude.
The incident, later blamed on a computer glitch, left 74 passengers with fractures, lacerations and spinal injuries.
The Australian Transport Safety Bureau (ATSB) director of aviation safety investigation Julian Walsh said the plane was travelling at 37,000 feet and 177km north of Carnarvon when it suddenly climbed 300 feet and then abruptly pitched nose down.
