What's /dev/pts? You mentioned you intended to use NFS as  root  file
system. Then I'd expect to see /dev/nfs here. [Note: 'n' != 'p']

You mentioned you intended to use NFS as root file system.  Then  why
do you use a ramdisk?

Your ramdisk image is much bigger than  the  default  maximum  kernel
ramdisk  size (4 MB). But you don't pass any ramdisk size information
with your boot arguments:

If you really want to use this  ramdisk,  you  should  set  the  root
device and the ramdisk size appropriately.
