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=,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=,local_lock=none,addr=XXX.XXX.XXX.XXX)

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report[0]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug.

Please follow the instructions on the wiki page[0]. The first step is to email the appropriate mailing list. If no response is received, then a bug may be opened on bugzilla.kernel.org.

Once this bug is reported upstream, please add the tag: 'kernel-bug-reported-upstream'.

I can confirm the same issue in Xubuntu 18.04.

(Should I submit my logs or open a new issue?)
