uPP EOW Interrupts

I have built up an application based on the sample code that came with the uPP Driver when I installed it.  The application has been modified to do two 16 bit receives. I get the first of set interrupts (one interrupt for I and one interrupt for Q), but don't anymore interrupts after that.  I reload the descriptors in the callback.  Below is a code snippet from my EOW interrupt callback:

    if (upp_isr_bit == CSL_UPP_UPISR_EOWI_MASK)

    {

                        //bufferIndexA++;

        if ((upp_reg_ptr->UPIS2 & CSL_UPP_UPIS2_PEND_MASK) == 0)

        {

            bufferIndexA++;

            upp_xfer_a.windowAddr = &upp_buffer_a_16[bufferIndexA][0];

            GIO_read(upph, &upp_xfer_a, NULL);

        }

        eowIFlag = 1;

    }

    if (upp_isr_bit == CSL_UPP_UPISR_EOWQ_MASK)

    {

                        //bufferIndexB++;

        if ((upp_reg_ptr->UPQS2 & CSL_UPP_UPQS2_PEND_MASK) == 0)

        {

            bufferIndexB++;

            upp_xfer_b.windowAddr = &upp_buffer_b_16[bufferIndexB][0];

            GIO_read(upph, &upp_xfer_b, NULL);

        }

            eowQFlag = 1;

    }
