ZC702 kernel can't print VFS info so that I cant not mount filesystem

The following context is my uboot and kernel print info, the uboot can launch kernel, but the kernel can not print VFS info and ALSA device list info 

This confused me long time and I google a lot but the questiong is remaining. Who can help me?

As can be seen above, the info stream is done after print "of_cfs_init: OK", there is no print info about the contents of the red box bellow

The ALSA device list and VFS info
