SDIO DMA times out

Hi all,
Using cube4.2.0 and STM32F205:
I am trying to use SDIO in DMA mode.
Polling mode work perfectly, but using "HAL_SD_ReadBlocks_DMA()" times out.
I have traced that "SDIO_IRQHandler()" fires and sets the "hsd->SdTransferCplt" flag, but "DMA2_Stream3_IRQHandler()" doesn't fire, therefore never sets the "hsd->DmaTransferCplt" flag, indicating an issue with the DMA.
From what I can tell, Cube has set up the DMA and ISR properly, but am I missing something else??
