bug#34091: 25.2; save-buffer fails to save to an NFS drive in Emacs 25 |

If I open an existing file in Emacs 25 (and Emacs 24), modify it and
attempt to save using C-x C-s (save-buffer), the file does not save. I
get the message "Saving <filename>...", but the file does not save and
remains marked as modified. If I attempt to save it with C-x C-w
(write-file), it prompts me for the name, and if I overwrite the file,
it succeeds. At that point, I can use save-buffer successfully until I
kill the buffer.
This only happens on a NFS mounted drive. If I do the same operation on
a local file system, it succeeds. The problem does not occur with Emacs
23 on the same NFS file system and the same host machine.
This problem occurs with a direct NFS mount, or with autofs automounting
the NFS partition.
The mount command shows the following setup for the automouted NFS partition.
lco-cssg-nas-17:/export/volDH00/dona on /home/dona type nfs (rw,nosuid,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=10.30.145.230,mountvers=3,mountport=20048,mountproto=tcp,local_lock=none,addr=10.30.145.230)
