The patch seems to solve the problem as nfs behaves as it did prior to -r1.188. Thanks. But there's still something wrong: When shutting down the server it still sometimes panics in vinvalbuf() complaining 'bout dirty pages. On the client side vi dies of SEGV (edited file and /var/tmp/vi.recover on nfs fs) generating a wrong sized recover file. After that the server panics on shutdown. Without triggering the bug it shuts down gracefully. I'll try to receipe a situation for easily reproducing this.
