I am facing issues while taking still continuously in imx6 Quad. The resolution of the captured image is 13MP. I am noticing this issue in Android Marshmallow and Nougat releases. I am taking stills continuously using the default camera application. After a certain time dma_alloc_coherent call fails with -EBUSY. 


I have tried changing the cma value in bootargs

By default it was 384M. I have also tried 448M
