Since it's a new problem try re-calibrating your controls in AH and look for any spiking on the advanced tab where you set the scaling.
If your hardware is good the best fix is simply to move your controls slower. You can try adding damping or scaling to see if you prefer that but you'll need to figure out which axis is causing the message.
I used to lock up from moving my rudder pedals until I noticed how slowly the rudder moves regardless of pedal input.
