List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: nfs-bounces@lists.sourceforge.net Errors-To: nfs-bounces@lists.sourceforge.net I couldn't get the nfs server running on one of my machine, and by looking in dmesg, seams like there is a kernel problem. I use a 2.6.16.20 vanilla kernel but i remember getting the same error with a 2.6.17 kernel too, a week ago when trying to run rpc.nfsd. I couldn't get any pattern to reproduce it yet but i got it more then once.
