[regression] nfs-kernel-server fails with 2.6.28

[Kees Cook]

Booting fails (I use NFS home directories). Portmapper is running, but nfs-kernel-server breaks:

Dec 17 22:17:11 gorgon kernel: [ 74.660056] RPC: failed to contact local rpcbind server (errno 5).
Dec 17 22:17:41 gorgon kernel: [ 104.660031] rpcbind: server localhost not responding, timed out
Dec 17 22:17:41 gorgon kernel: [ 104.660054] RPC: failed to contact local rpcbind server (errno 5).

$ rpcinfo -p localhost
   program vers proto port
    100000 2 tcp 111 portmapper
    100000 2 udp 111 portmapper
    100024 1 udp 56296 status
    100024 1 tcp 49528 status

Reverting to 2.6.27-10 fixes it. Both -2 and -3 of 2.6.28 exhibit this behavior.
