FSL UART Driver in Blocking Mode with MQX

I am using the FSL UART Driver in blocking mode with MQX as the RTOS.  When the IRQ posts to the rxIrqSync semaphore a hard fault is generated.  Have spent three days troubleshooting this problem and have run out of ideas as to what to try next. The _lwsem_post code executes to the _CHECK_RUN_SCHEDULER() function where the hard fault occurs.


Any troubleshooting suggestions would be greatly appreciated.
