(Get the code!)
David is right here. One of the bugs mentioned by Thag seems even gone since a while (the last comments I see are from 2008). The other bugs seem to relate to a server side NFS lockup and seemed to produce stack traces on the server. Reading there it seems that this issue should be fixed now and that fix was part of 2.6.32-20.29 for Lucid and the initial release of Maverick.
So we should concentrate on receiving files in this bug report. If I understand correctly the server side is unaffected and shows no messages. And the client can re-connect after the reset?
David, if you could try to see whether doing the file copy on the text console (vt1) shows some messages when locking up. And just to mention, yes surely using the user-space nfs server changes the problem (or maybe avoids it). It is completely different code (and presumably slower). But it may as well be only the client side and it would be good to find the problem there. And to understand it better we need to find out how to trigger it reliably (and hopefully get some data out of it).
