High speed UART with DMA

I'm working on a STM32F4 mcu and I'd like to use an UART with a baud rate of 1843200bps with a DMA that works for every byte received on this UART. Using CubeMX I have created an example code with a UART 1843200bps, 8 bit, no parity and 1 stop bit; the DMA clock frequency is 84MHz, using the external 8MHz quartz and the internal PLL. My problem is the interrupt does not set every byte received and so I can't receive any frame from the outside. Please, could you suggest me a solution ? Kind regards Davide Urbano,
