I don't believe there is a DMA regression for you to look at, this was solved a long time ago thanks to Robin, here is the beginning of the thread: https://lore.kernel.org/lkml/ca+g9fyvuq58q+gswnzni0skshbubuqz-uak3tasx26v_a7y...@mail.gmail.com/ -- Florian

I tried to reproduce, without luck, with another NAND controller. If someone has an imx based board and a NAND controller on it, I would appreciate some help. Thanks, Miquèl

I had originally reported it for an imx27 board and now I also pointed out that it also affects Layerscape: https://lore.kernel.org/linux-mtd/20201013193652.0c535c7c@xps13/T/#m09fad7eacdf86aee0834bbd8863d6d5ee2e69f8c Thanks, Fabio Estevam
