In order to reproduce the kdump tool readlink failure it is possible to
execute:
$ sudo kdump-config unload
$ sudo rm /var/lib/kdump/initrd.img-$(uname -r)
$ sudo kdump-config load

```
Again, since I was able to reproduce the issue without updating the
kernel, this seems to be a problem which has not been cause by the
kernel update itself.
The reason why kdump-tools is generating this amount of failures must be
investigated further.
