Now I think I have found the commit that fixes the issue by reverse bisecting first kernel versions and the commits.
Since it is a reverse bisection it says first bad commit instead of good commit:
# first bad commit: [e92c1e0d40c50472f80820bd829645ce9fefd6c1] NFSv4: Fix a nograce recovery hang
See also attached containing output from 'git bisect good' and 'git bisect log'
