In Naresh' example, root is on NFS:
root=/dev/nfs rw nfsroot=,tcp,hard,intr on / type nfs (rw,relatime,vers=2,rsize=4096,wsize=4096,namlen=255,hard,nolock,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=,mountvers=1,mountproto=tcp,local_lock=all,addr=
devtmpfs on /dev type devtmpfs (rw,relatime,size=3977640k,nr_inodes=994410,mode=755)

Following message repeats couple times in logs:
NFS: Server wrote zero bytes, expected XXX

Naresh, can you check if there are any errors on NFS server side?
Maybe run NFS cthon against that server with client running next-20190822 and next-20190823.

It appears to be mixed in same log file:
