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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1650336 Title: NFS client : kernel 4.4.0-57 crash with nfsv4 enries in /etc/fstab To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1650336/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
