It seems to be the wrong = approach :

This is a wrong approach, while they have the same SoC and most of the =
peripherals are 
the same they are not the same board and this can =
only lead to problems.

So I suppose that the fix hasn't been upstreamed for FreeBSD =

What can I do to bypass the bug ?
