i.mx7: Changing linux,usable-memory causes BUG: Bad Page

I am using an i.mx7d based board, and attempting to reserve the lower
2MB of memory for the M4 co-processor.

I have changed the textofs-y to 0x208000 to move the kernel extraction
past the first 2MB, and everything seems to function correctly. Then,
after changing the linux,usable-memory, I get a Bad page BUG. The BUG
is the same on every boot, with the same exact two bad pages.This
article points to a memory integrity issue:
http://archive.armlinux.org.uk/lurker/message/20140729.201750.e26283f6.en.html.
I've performed overnight memory stress tests and haven't seen any
signs of memory
corruption, and the bad pages are the same every time.

The change that causes the BUG is shown below.

memory {
        device_type = "memory";
        reg = <0x80000000 0x40000000>;
-        linux,usable-memory = <0x80000000 0x3ff00000>;
+       linux,usable-memory = <0x80200000 0x3fdf0000>;
};

reserved-memory {
        #address-cells = <0x1>;
        #size-cells = <0x1>;
        ranges;

        linux,cma {
                compatible = "shared-dma-pool";
                reusable;
                size = <0x14000000>;
                linux,cma-default;
        };

        m4 at 80000000 {
                reg = <0x80000000 0x200000>;
        };

        rpmsg at BFFF0000 {
                reg = <0xbfff0000 0x10000>;
        };
};

Here is the dmesg that includes the BUG with memblock=debug
