just adding to this: i seem to have the exact same problem, only i
wasn't describing it as verbosely [1]. so setting telemetry to
raw_sensors and observing the ACC/GYRO/MAG values the former two are ok
but MAG values don't change (in about 8 out of 10 power
cycles, lisa/m v2, aspirin v2.2, current master).
