Thanks for taking the time to look at this, and sorry to have missed
that my BIOS was out of date. I have now flashed the new version and
running the commands as you propose gives the following output:
nick@serv2:~$ sudo dmidecode -s bios-version && sudo dmidecode -s
bios-release-date
[sudo] password for nick:
P1.40
07/23/2015
Also, I confirm that updating the BIOS has not solved the problem.
If I understand your question correctly, you are asking for how the bug
manifests itself? If so, I have the following two files set up on my MAC
to allow me to automount the share:
beethoven:etc nick$ cat auto_master
#
# Automounter master map
#
+auto_master # Use directory service
/net -hosts -nobrowse,hidefromfinder,nosuid
/home auto_home -nobrowse,hidefromfinder
/Network/Servers -fstab
/- -static
/- auto_nfs -nobrowse,nosuid
and
beethoven:etc nick$ cat auto_nfs
/../Volumes/share -fstype=nfs,noresvport nfs://serv2_local:/export/share
Note for completeness, serv2_local is defined in my /etc/hosts file:
beethoven:etc nick$ cat /etc/hosts
##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
##
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
fe80::1%lo0 localhost
192.168.2.4 serv2_local
(and that I have a good connection to it:
beethoven:etc nick$ ping serv2_local
PING serv2_local (192.168.2.4): 56 data bytes
64 bytes from 192.168.2.4: icmp_seq=0 ttl=64 time=4.572 ms
The use of /../Volumes/share is a trick to make OSX automount in the
/Volumes directory. I have tested using /mnt/share and get the same
error.
serv2_local is also correctly exporting the nfs shares:
beethoven:etc nick$ showmount -e serv2_local
Exports list on serv2_local:
/export/pvr 192.168.2.0/24
/export/share 192.168.2.0/24
/export/home 192.168.2.0/24
/export 192.168.2.0/24
(note that the MAC I am using has IP address 192.168.2.42 so it should
be able to access the export)
When I try to access the shared directory, I get the following:
beethoven:Volumes nick$ cd /Volumes
beethoven:Volumes nick$ ls -lh
total 10
lrwxr-xr-x 1 root admin 1B 24 Oct 17:13 Macintosh HD -> /
dr-xr-xr-x 2 root wheel 1B 24 Oct 17:13 share
beethoven:Volumes nick$ cd share
-bash: cd: share: No such file or directory
If I boot the Ubuntu server with the pervious kernel version, I am able to
access the NFS share normally.
Thanks for taking your time to look at this -- let me know if you need
more information.

Title:
I cannot mount nfs shares from osx when using the new kernel
Status in linux package in Ubuntu:
Confirmed
Bug description:
I am running ubuntu server 64 bit 14.04 on my home server.
The server shares some directories using NFS v4
I have some apple macs (MBAs) that use the automount to mount the shared nfs
directory. Previously, this had worked fine.
My file /etc/auto_nfs contains the single line:
/../Volumes/share -fstype=nfs,noresvport nfs://serv2_local:/export/share
I updated to kernel 3.13.0-66 and the OSX machines would no long mount
the NFS shares (see message below from /var/log/messages.log on the
Mac):
Oct 24 14:34:35 beethoven automountd[655]: NFS server serv2_local not

My other linux clients were able to mount the NFS share without difficulty. I
have rolled the server back to the previous kernel (3.13.0-65-generic) and NFS
works fine with the Macs. (Note that the problem exists with both my Macs,
running OSX 10.10.5 and 10.11.1)
