Pixhawk AutoTune crash

Hello,

My hexacopter crashed a few days ago and I cannot find out why exactly. It was after I tried to autotune it, I don’t know if it could be the reason. Here is a list of things I found out during the flight and in the flight logs:

1: At the end of the flight, the copter’s roll wasn’t responding at it should have.
2: It disarmed at the end of the flight because the crash check activated.
3: I checked the servo power rail and it seemed fine.

I know why it crashed (crash check), but I don’t know what happened to the roll of my copter for it to fail.

I joined the flight logs via a DropBox link from the Pixhawk and I hope you’ll be able to help me.
Firmware on the Pixhawk is AC3.4.6

Thank you
