Report the problem to your distribution provider, Atmel in this case.

I cannot say anything WRT the redhad stuff. Much prose there but I did 
not find a patch that would indicate how they fixed the problem. So I 
cannot tell if their fix is fine or just a hack and the issue might pop 
up in a different context again.

If the "fix" is just a work around in the sources, you will see the 
problem and wrong code in other contexts and with other user code, too, 
of course.
