[Bug 48675] rpc.nfsd generates oops

Public bug reported:
Binary package hint: nfs-kernel-server
I upgraded my NFS server at home to Dapper (from Hoary) and have started
getting oops'es from rpc.nfsd.
I've tried both the user and kernel versions of the nfs server and it
oops'es in both cases, though when I use the user-space version the
machine doesn't always need to be rebooted.
This only happens under heavy load, but it never happened before I
upgraded to Dapper.
