What's your client, and what version of the NFS protocol are you using?
The client is STLinux: # uname -a Linux stb 2.6.23.17-stm23-0123 #1 PREEMPT Tue Sep 10 16:42:52 CEST 2013 sh4 GNU/Linux using whatever version it defaults to (my guess v3) while mounting rootfs over NFS.

Double-check that, it might be v2, in which case you need to edit /etc/sysconfig/nfs on the server to pass -V2 to rpc.nfsd, or fix the client-side configuration.
Adding RPCNFSDARGS="-V2" helped and mounting succeeded. Thanks. :-) So, some behavior was changed between these two kernel versions. Should it be documented or defaulted differently?
*********** MASS BUG UPDATE ************** We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 19 kernel bugs. Fedora 19 has now been rebased to 3.12.6-200.fc19. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you have moved on to Fedora 20, and are still experiencing this issue, please change the version to Fedora 20. If you experience different issues, please open a new bug report for those.
