I also tried Upstream v4.4.15 (35467dc7630af60abacc330f64029d081f160530)
which does not have the issue. Going to bisect shortly.
** Summary changed:
- NFS client: access problems after updating to kernel 4.4.0-31-generic
+ [regression] NFS client: access problems after updating to kernel
I am having the same problem here as well since 4.4.0-31. Have not tried
mainline.

Title:
NFS client: access problems after updating to kernel
Same problem. Reverted to 4.4.0-28. Didn't try mainline as -28 was
sufficient.

Title:
NFS client: access problems after updating to kernel
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.

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
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
Same problem reverting to 4.4.0-28 fixed the problem

To manage
apport information
** Tags added: apport-collected
** Description changed:
I am denied access to the subfilesystems exported by my nfs server (the
top level filesystem itself is unaffected).
The client is reporting that I do not have the necessary permissions.
However, all was fine
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/srvnfs4
Jurgen Schellaert, thank you for reporting this and helping to make Ubuntu
better. Please execute the following command only once, as it will
automatically gather debugging information, in a terminal:
apport-collect 1603719
When reporting bugs in the future please use apport by using 'ubuntu-
