This happens with: hwpack_linaro-imx51_20110726-1_armel_unsupported.tar.gz
dmesg output as below. MMC/SD didn't seem to be enabled and that could be the cause.

Gave up waiting for root device.  Common problems:
 - Boot args (cat /proc/cmdline)
   - Check rootdelay= (did the system wait long enough?)
   - Check root= (did the system wait for the right device?)
 - Missing modules (cat /proc/modules; ls /dev)
ALERT!  /dev/disk/by-uuid/bc24ee41-2b57-46bd-b75c-4a272b94ef5a does not exist.  Dropping to a shell!
