ST32F103ZE Uart Interrupt problem

I am communicating in/out a USB - via UART5 Serial port. I also have another device connected to the AtoD port. I can run either alone fine, but once I plug in the AtoD device after a varying amount of time the code hangs in the UART5_IRQHandler, where USART_GetITStatus(UART5, USART_IT_RXNE)  is always = to RESET.

Each device is, to the best I can tell, completely independent as far as the code is concerned, so, I don't see a way that they could be interfering with each other.

Let me know if anyone has seen / solved this problem.
