Hum, interesting. It is not the first time we have report from people
saying that fairly big filesystems cause failures while generating the
ext2 image. I don't know if it's a genext2fs problem, or if it's our
script that computes the number of inodes and blocks needed that does
something wrong. Would be good if someone could have a look into this.

make menuconfig
 -> Target filesystem options
   -> disable 'ext2 root filesystem'

Works here. It doesn't work for you ?
