Embedded computers in aircrafts

Posted: September 27th, 2009 | Author: | Filed under: Debugging | 3 Comments »

I am back from vacations and had a 11 hours flight with AirAustral. On board each seat has an embedded computer. With this computer, you can watch movies, play games, …

This machine is running on Linux which is downloaded and executed using Redboot as you can see in the following picture:

The hardware appears to be from Panasonic Avionics Corporation, probably a Panasonic X Series:

How did I made this picture?: I found a bug that caused the computer to deadlock. I tested it on 4 machines in 2 different aircrafts: 100% reproducible.

Steps to reproduce:

  1. Go in the Games section.
  2. Start the game ‘Who wants to be Millionaire?’.
  3. Play one game.
  4. Quit the game.

Result:

The machine will display a message “Please wait…” and a deadlock will occur.
You then need to ask a stewardess to reboot your machine. The reboot is quite slow and takes around 5 minutes.

PS: I don’t know where to send the bug report 🙂
