Thank you for your effort Unfortunately the tests are very confusing
With the two shares from the FreeBSD 11 Server the mainline kernel 4.10.0 has no problem !!! Also if i try to mount two additional shares from another FreeBSD 11 Server. No Problem at all ! But if i am try to mount the two shares from the ubuntu 14.04.01 nfsv4 server only one share will mounted at boot time but after the timeout expired it fully boot. With the mainline kernel 4.9.4 the computer boots in every combination an numbers of shares without problem just like 4.8.17 mainline kernel and the 16.04.01 installation source kernel 4.0.31 Mainline kernel 4.4.43 crash just like 4.4.42 and 4.4.41 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1650336 Title: NFS client : kernel 4.4.0-57 crash with nfsv4 enries in /etc/fstab Status in linux package in Ubuntu: In Progress Status in linux source package in Xenial: In Progress Bug description: On (K)ubuntu 16.04.01 (Xenial) Upgrading to kernel 4.4.0-57 the kernel crash on boot when in /etc/fstab a nfsv4 entry is active When comment the line or set to noauto the kernel boot with no error and mounting the nfs shares (after uncomment ) is also possible without error 4.4.0-54 boots without this problem.
