I preferred to use the version 2.6.24  which is shipped with the board=20
because the manufacturer can provide support in case of trouble.
But, I compiled and tested the version 2.6.35 and it's running fine at=20
first but the dmesg output is corrupted with a lot of "BAD IRQ".
I thought that this version was not really stable yet and I don't have
enough time in my project to ensure it. That's why I preferred to use
the version 2.6.24.

If a bug is happening with our application, I will definitely move
to the most recent one.

Best regards,
