growfs needs a serious rewrite.  Unfortunately, I didn't have the time to 
really look at it.

I know this error very well.  I can trigger it even on smaller drives when 
growing the FS so much that the cylinder summary needs to be relocated 
because it won't fit into one block anymore.  Surprisingly, I can then run 
an fsck and growfs again and it works.
