I was out doing some test flights earlier, and seeing some strange behavior.
Flight flight:
https://review.px4.io/plot_app?log=28e18a9d-a601-4244-8d96-a0f1a5301ed9
Around 2:15. There is a large twitch on roll, settles out and lands safely.
second flight:

around 4:45. Notice the large spike to the east. This did NOT happen. While flying there was what appeared to be a glitch on roll, resulting in a sharp motion to the west. Once this happened I took manual control and landed safely.
Third flight:

Around 9:55.
Coming in for a landing. Violent roll oscillation starts and ends up crashing into a snow bank.
Any idea what went wrong here? One disturbing theme I have noticed is that the problems seem to occur simultaneously with a logging dropout and a spike in CPU load.
