Can you indicate your /proc/mounts content indicating this, are you 
symlinking /etc/mtab to it?  For reference, I'm not having this problem 
when mounting with mount.nfs, adding 'fsc' flag, and performing 
switch_root from within an initramfs.  Might it be a simple issue with 
/etc/mtab, or possibly lingering cruft if you don't mount with "-n"?

Here's my shortened /proc/mounts output for the point:

   rootfs / rootfs rw 0 0
   10.1.2.3:/path / nfs 
rw,vers=3,hard,nolock,fsc,proto=udp,sec=sys,addr=10.1.2.3 0 0
