CF is on USB. USB probing may not have finished when the kernel wants to mount
the root file system. Usually the initrd takes care of waiting until the
root device is there.

Does it work if you add e.g. `rootdelay=10' to the kernel command line? 

Cfr. Documentation/kernel-parameters.txt:

	rootdelay=	[KNL] Delay (in seconds) to pause before attempting to
			mount the root filesystem
