I would say it seems that your /dev/nand0.kernel.bb is not big enough
for the kernel image, so the kernel doesn't fit in.

You have two choices:

1)
   Make the kernel smaller. This is more complicated and you should know
   what you doing there. In ptxdist kernelconfig disable some feature or
   compile with -Os.

2)
   Make the /dev/nand0.kernel partition bigger, which should much
   easier to be done. I suppose you have a barebox with a defaultenv in
   version one (You use the update script there).
   In the barebox shell type 'edit /env/config' and search for the part:

   nand_parts="256k(barebox)ro,128k(bareboxenv),3M(kernel),-(root)"

   In this example the kernel partition is 3M which stands for megabyte
   big. Try to increase your partition and reflash kernel and rootfs.
   You need to that afterwards because the kernel partition fill be
   overlapped with the root partition, so be sure you saved everything
   from the rootfs before you do that.

   One notice about the edit command, you can save it with "Ctrl-D" and
   type "saveenv" afterwards. Then reset the board.
