What are you doing with the physical address of a varaible that is on
the *stack*?  If you let some hardware modify that value, then you can
easily trash your stack if the hardware modifies this value *after*
this function exits since tmp will go out of scope.

I'd suggest that you move tmp outside of func for starters.
