[U-Boot] Getting "Unable to save the rest of sector (196608)" when I turn on Redundant env with CFG_ENV_ADDR_REDUND

I guess I don't understand at all why flash_addr_new + CFG_ENV_SIZE is
getting saved off when I want my redundant environment to start at
flash_addr_new.

So, I went back to the other test case I'm trying where my
CFG_ENV_SIZE is equal to flash sector size (256k in my case) which
makes the redundant environment work but when I try to NFS boot my
board I get:

And then everything hangs.  Should I play with moving around TEXT_BASE
(0x05000000), linker files?  I'm kind of stumped at the moment. :(
