Bizarre MPU9250 behaviour
I’ve recently tried adding an MPU9250 for heading and attitude information. However, it shows up on the I2C address list and provides valid data for around 10-30s after connection or boot, but then stops sending data and the I2C address list becomes a mess of random addresses that aren’t connected. 

I suspect it’s a dodgy MPU, but before I send it back does anyone know what the hell is going on?
