I make a tcpdump if needed. I see the issue too with an ARMv5 based DM355 board with the just released v2.6.37 tag (nfs client). I too see the issue when using bash tab completion. Here are some logs: fileid changed fsid 0:c: expected fileid 0x2db61d, got 0x2dad20 fileid changed fsid 0:c: expected fileid 0x100000000000, got 0x7070000000000000 I am using Fedora 8 (2.6.25 kernel) on the server side. I will try the latest Ubuntu release on the server side and test.
