Bug Description
I am testing the development branch of Bionic Beaver.
With the latest update to kernel 4.15.0-13 my nfs-mounts in a university network are broken.
> sudo mount -vvv -t nfs4 my_server:/my/share /nfs -osoft,sec=krb5
> mount.nfs4: timeout set for Mon Mar 26 16:29:56 2018
> mount.nfs4: trying text-based options 'soft,sec=
> mount.nfs4: mount(2): Input/output error
> mount.nfs4: mount system call failed
> kernel: NFS: nfs4_discover_
> kernel: RPC: couldn't encode RPC header, exit EIO
> kernel: gss_marshal: gss_get_mic FAILED (851968)
Known good version: linux-image-
I think it is the same bug like in https:/
The bug was introduced in the mainline kernel 4.15.4 with commit "[46e8d06e423c4
This bug should be fixed before releasing ubuntu18.04 by either reverting the commit or using a fixed mainline kernel.
