mSGDMA stride reads/writes

I just want to do a continuous read, and want the write address to roll over after so many bytes or reset back to the base address. As an example, I want to transfer 2 MByte of data, to a 256 bit wide FIFO. I understand I could probably just chain up many small descriptors and increment the address in software, but why should I have to do that, the DMA engine should be capable of handling this. When the stride feature is enabled, the system always ends up in an irrecoverable state and the only way to fix that is to reprogram the FPGA and restart the PC.
