I am able to reproduce the issue with the latest mainline kernel
installed.

Title:
  NFS client readdir loop

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Apparent duplicate of this expired bug, reproducing on 12.04 LTS which
  is still supported.

  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1026139

  I get several errors of the following form on the client side of an
  NFS4 mount. I Issue may be related to the large number of files in the
  mount point, there are about 150K in there.

  NFS: directory xxx contains a readdir loop.Please contact your server
  vendor.  The file: xxx has duplicate cookie xxx

  The software fails with " Too many levels of symbolic links". No
  errors appear on the server log.

  3.- I expect the software to access the files and no readdir loop
  errors to occur

  4.- Software fails with Too many levels of symbolic links, kernel logs
  NFS: directory xxx contains a readdir loop.Please contact your server
  vendor.  The file: xxx has duplicate cookie xxx

  No apparent problems are present on the server and I can share out the
  same filesystem via SMB without any issues.

  Attaching ubuntu-bug, version signature and lspci from both client and server side.
