Almost certainly, the rootfs thinks it's supposed to be able to write  
to the top of flash where your kernel uImage is.  Did you load an  
older rootfs which thinks there are only 2 regions of flash {u-boot,  
rootfs} rather than three {u-boot, rootfs, uImage}?

Can you re-load the uImage and rootfs, restore them to the flash,  
then boot again, and this time save the boot log.  I'm particularly  
interested in the part where it's talking about flash partitions.
