This bug was fixed in the package makedumpfile - 1:1.6.0-2

---------------
makedumpfile (1:1.6.0-2) sid; urgency=medium

  * define_stampdir() : Loop on hostname -I for 5 sec to get IP address
    if HOSTTAG=ip. The network stack may not be ready when kdump-config runs.
    Give it some time before reverting HOSTTAG to hostname if an IP address
    cannot be found. (LP: #1599561)

  * debian/rules : drop the dh_installinit override
    Uses a syntax which is no longer supported and generate an error on
    install. (LP: #1599491)

Bug description:
  == Comment: #0 - PAVITHRA R. PRAKASH - 2016-06-30 07:12:40 ==
  ---Problem Description---

  During kdump over ssh IP prefix will be present only in first dump,
  subsequent dumps will not have IP in directory name.

  ---Steps to Reproduce---

  1) apt-get install linux-crashdump
  2) increase crashdump size:
  sudo vim /etc/default/grub.d/kexec-tools.cfg

  GRUB_CMDLINE_LINUX_DEFAULT="$GRUB_CMDLINE_LINUX_DEFAULT crashkernel
  =2G-4G:320M,4G-32G:512M,32G-64G:1024M,64G-128G:2048M,128G-:4096M

  3) sudo update-grub ; reboot the machine
  4) sudo sed -i 's/USE_KDUMP=0/USE_KDUMP=1/g' /etc/default/kdump-tools
  5) kdump-config show # should show "ready to dump"
  6) ssh-keygen -t rsa
  7) Edit below parameters in /etc/default/kdump-tools
  SSH="root@<server IP>"
  SSH_KEY=/root/.ssh/id_rsa
  8)  kdump-config propagate
  9)  kdump-config show
  10) reboot
  11) echo "c" > /proc/sysrq-trigger
  12) verify dump is created in ssh server.
  13) trigger the crash again.

  Canonical,

  The behavior appears to be somewhat intermittent, and it looks as if
  define_stampdir() might be getting called before the network init has
  completed.  If delaying this function is not practical, it might be
  helpful to have define_stampdir() fall back to using just "hostname"
  if "hostname -I" doesn't return any useful information for setting
  THIS_HOST.
