Hi Kevin,
When the system locks up, does it get stuck in the FifoRecvHandler()
routine?
How many bytes are returned from XLlFifo_RxGetLen(&lp->Fifo) in that
routine?
You can try calling XLlFifo_Reset(&lp->Fifo); to see if that clears the
fifo. Though, I suspect that this wont fix the root cause of the problem
you're seeing.
