Hi, 
    I booted it inside a hardware board(freescale imx51).I think you need to rebuild your kernel modules file.Just like,make ARCH=arm CROSS_COMPILE=arm-iwmmxt-linux-gnueabi- INSTALL_MOD_PATH=${TESTROOTFS}
then,you should copy your "TESTROOTFS" in /lib/modules which is in fedora rootfs.

Regards,

Hi tuxdna,
    I rebuilded a new kernel image and copy the modules file in /lib/modules/.Finaly I removed the dhclient which is in /usr/bin/ and I can always boot the rootfs from the nfs server.   ^_^ 

Where are you booting it, inside QEMU or inside some hardware board?
Does it still hang ?

For me it doesn't hang inside QEMU. I haven't checked on a hardware board yet.
