Sorry, no changes ... but i noticed something that could be usefull. To ensure there is no hardware problem on my computer, i installed a fresh kubuntu 16.04.01 on a newer maschine and configured it.
Same behaviour ... the base kernel from installation 4.4.0-31 work without problem ... but all newer kernels i tested there crashes sometimes, also the 4.4 mainline kernels :( Sometimes, when disconnecting power for some minutes the mainline kernel boot successfully ... In the boot logs i see the mount of the first nfs entry seems to be successfull, the kernel crashes when trying to mount the second entry ... With or without kerberos ... i tried several combinations ... having only one nfs entry in fstab booting without problem, adding the second one makes the kernel crash on boot time. Mounting a secound nfs share after boot is complete is no problem -- 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.
