Could you please take a look on it?
I'll apply the patch anyway, as at least it will reduce the stack size
and partially fix the issue, but, as Florian and Zdenek pointed, there
are still some cases were stack pointers are used to pass data to URB's,
and this is forbidden (and don't even work on some architectures).
Mauro.
