I think from your description that the ramdisk you've built is now too large to
fit into the ram set aside for it. Aside from the previous change to increase
the size of the ramdisk partition in NAND to 30MB, you can increase the amount
of reserved kernel memory for it in u-boot by:
setenv ramdisksize 75000
which increases the memory for the ramdisk from ~64MB to ~75MB.
Again, "savenv" after updating ramdisksize will save the change for
the next reboot...
