I just removed /proc and /sys on CF and boot from CF. There was something difference. In the previous case, the screen just stopped after progress bar turned to all white. In the later case (after removed the two dirs), after progress bar turned to all white, iLiad seems to boot again automatically, but this time it boot from root partition on iLiad.

Does it mean that bootloader can go further in the previous case? In this case, bootloader found root partition on cf was ok, so bootloader transferred execution right to root partition on cf, and system just failed because incomplete root partition. In the later case, bootloader found that there was no /proc and /sys on cf, so bootloader decided to reboot without cf.
