I've just upgraded a Hardy machine to Jaunty and experienced this problem. Kernel is 2.6.28-11.
On the machine in question, I'm still using nfs v3, so the NEED_STATD=no workaround did not help.
I think I've solved it by installing the "statd" package and starting that daemon.
Haven't had a chance to use it properly in anger yet though, so can't guarantee that my solution is stable/reliable.
