Title:
  If NFS server reboots, client somethings fails to remount the file
  system properly

Status in nfs-utils package in Ubuntu:
  New

Bug description:
  If the NFS server reboots, sometimes client servers fail to re-
  establish the NFS mount properly.  This is using NFS v4.2.  The client
  machine will hang if I try to do a df when an NFS mount is in this
  condition.  Attempting to access a file will likewise hang
  indefinitely.  This is a problem with the stock 5.3.0.x kernel and it
  is a problem with 5.6 still.  I have not tried 5.7 yet.  I filed this
  against nfs-kernel, but I am not 100% sure it is not nfs-common but
  there is some sort of communications not happening between them.
