I experience the same issue:

Kernel on the nfs client:
#> uname -a
Linux ar 4.4.0-31-generic #50-Ubuntu SMP Wed Jul 13 00:07:12 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

Here's the fstab line for the nfs4 mount:
server:/ /network/srv nfs4 noauto,user,x-systemd.automount,x-systemd.device-timeout=10,x-systemd.idle-timeout=0,rw,sec=sys,relatime,vers=4.2,hard,intr,proto=tcp,timeo=30,retrans=2,port=2049,x-systemd.requires=nfs-client.target 0 0

#> ls /network/srv
music videos

#> ls /network/srv/music
/bin/ls: cannot open directory '/network/srv/music': Operation not permitted

Kernel on the NFS server:
#> uname -a
Linux ossrv 4.4.0-21-generic #37-Ubuntu SMP Mon Apr 18 18:33:37 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

Here's the /etc/exports file on the NFS server:
/export 192.168.0.0/16(fsid=0,rw,crossmnt,insecure,no_subtree_check,async,anonuid=65534,anongid=65534)
/export/music 192.168.0.0/16(rw,crossmnt,insecure,no_subtree_check,async)
/export/videos 192.168.0.0/16(rw,crossmnt,insecure,no_subtree_check,async)

When i boot the kernel version 4.4.0-28-generic (or before) on the NFS client is working fine.

Same problem reverting to 4.4.0-28 fixed the problem

Same issue on this kernel. Cant browse subdirectories that are mounted hdds after kernel update. Downgrading fixes the issue.

Ex can browse /mnt but cant browse /mnt/hdd1 /mnt/hdd2 etc

If im root i can browse the subdirectories though just not as a standard user. Verified permission and works fine on a kernel downgrade. After root user has browsed a nfs subdirectory a standard user can browse it.

Also able to browse the subdirectories if I mount each hdd individually. Ex if I mount on client /mnt/hdd1 instead of mounting /mnt

Jurgen Schellaert, in order to allow additional upstream developers to examine the issue, at your earliest convenience, could you please test the latest upstream kernel available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please keep in mind the following:
1) The one to test is at the very top line at the top of the page (not the daily folder).
2) The release names are irrelevant.
3) The folder time stamps aren't indicative of when the kernel actually was released upstream.
4) Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds .

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, and Y are the first two numbers of the kernel version, and Z is the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream.

Also, you don't need to apport-collect further unless specifically requested to do so.

Once testing of the latest upstream kernel is complete, please mark this report Status Confirmed. Please let us know your results.

Thank you for your understanding.

Thanks for your helpful instructions.

The most recent mainline kernel (= 4.7.0-040700rc7-generic) appears to be unaffected.

I can now enter the exported subfilesystems again with the expected permissions.

Same problem. Reverted to 4.4.0-28. Didn't try mainline as -28 was sufficient.

I am having the same problem here as well since 4.4.0-31. Have not tried mainline.

I also tried Upstream v4.4.15 (35467dc7630af60abacc330f64029d081f160530) which does not have the issue. Going to bisect shortly.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-xenial' to 'verification-done-xenial'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
