This looks like one of the issues in timers I have seen, although it's 
worse than what I would have expected. Current git master code should 
not have any problems there any more. Does Xilinx still ship 1.4.1 
(which is more than 7 years old by now)? If so, why don't the ones who 
pay them money make them use up-to-date source? If they run into 
problems, tell them to come here and get support in upgrading the stack :-)
