Title:
NFS client : kernel 4.4.0-57 crash with nfsv4 enries in /etc/fstab
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Xenial:
In Progress
Bug description:
SRU Justification
Impact: A commit from upstream 4.4 stable introduced a regression in
refcounting auth_gss messages which can lead to an oops.
Fix: Cherry pick upstream commit
1cded9d2974fe4fe339fc0ccd6638b80d465ab2c "SUNRPC: fix refcounting
problems with auth_gss messages."
Regresssion Potential: Test results confirm that the commit fixes an
existing regression. It's pretty straightforward and is already
present in some upstream stable kernels, so I think the potential for
regressions is minimal.

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.
