Title:
  16.04 LTS NFS4 Client hangs when copying large files

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  When doing simple copy-jobs with large files (f.ex. Partition Images > 4 GByte filesize)the file transfer allways stall after about 16 GByte has passed to the Client.
  No Problems using kernel-versions up to kernel 4.2 (Ubuntu 14.04 up to 15.10).
  Verified with new installations of 16.04 LTS as well as upgraded (previous working) 15.10 workstations to 16.04 LTS.

  Autonegotiated NFS-values are still the same:

  Working 15.10 version:
  server:/informatik/ab on /informatik/ab type nfs4 (rw,relatime,vers=4.0,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=krb5,clientaddr=134.100.9.19,local_lock=none,addr=XXX.XXX.XXX.XXX)

  Failing 16.04 LTS Version:
  server:/informatik/ab on /informatik/ab type nfs4 (rw,relatime,vers=4.0,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=krb5,clientaddr=134.100.9.19,local_lock=none,addr=XXX.XXX.XXX.XXX)
