Ok, good to know.
Please check your kernel config. The stock config isn't good at all. You need to look for CONFIG_CMDLINE option. Please remove this option because anything there will override the cmdline passed to the kernel from uboot. (ie: in my aura HD the rootfs=/dev/mtdblock2, which does not exists)
