These messages get triggered randomly (I suspect on unmounting NFS
mounts, which are managed by systemd automounter) on my Ubuntu 23.10
machines and end up in systemd journal and kern.log (gigabytes of
messages), system uses 4 CPUs completely and gets unresponsive.

  Those messages are not displayed when I boot my system with a mainline Linux 
kernel.
  Moreover, in the mainline Linux source code, I do not find the lines where 
such a message could be printed.

  Therefore, those messages are probably caused by an Ubuntu patch.
