Similar problem here, but ubuntu kernel 4.4.0-31 was not affected here, all kernels from there to the current 4.4.0-45-generic has the problem.
Today i found this thread and test the latest mainline, 4.4.27-040427-generic, this one works without problems :) NFS Server is FreeBSD 11, but also OmniOS r151018 Thx Thomas -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1604396 Title: Kernel 4.4.0-31 cd into NFS4 directory: Operation not permitted To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1604396/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
