Kernel tinification

We repeatedly had the same issue as you, soft crashes requiring a hard reset to fix. So we called in the engineer under warranty to fix it.

He looked outside, and said "Are you under a flight path?". We are, about three or four miles from City Airport, almost right under the normal approach. So the engineer said, "it's a well known problem, the flight avionics interfere with the controller. You'll need a new controller." He replaced it and it's been fine ever since ...

Cheers,
