All the faulty instruments, the ADIRUs, the ISIS and the TCAS appear to be inputed by Pitots, static ports or barometric pressure sensors.
The ISIS and IR2 faults were related to inertial reference faults/disagreements. I can't see how airspeed and barometric data would per se generate them.
If they were later caused by a "shaking to hell" a/c it's another story...
