I presume you mean that "parameters =" in /etc/zipl.conf should have
crashkernel=auto set.

Note that on ubuntu, we do not enable crashkernel by default, but we do
enable it upon installing kdump packages.

On the other hand, unlike other architectures we do not actually re-
generate /etc/zipl.conf from e.g. configs and kernels on disk. Thus I am
inclined to add crashkernel=auto by default. Louis Bouchard, what do you
think?

  Ekaterina (Kate),
  As a test, please reboot and then paste the output of
  a)  cat /proc/iomem
  b)  cat /proc/cmdline
  c)  cat /etc/zipl.conf

  Putting in needinfo state to KATE@xxxxxxxxxx .  I would like a simple
  test.  Reboot and check crashkernel parameter again before we mirror
  to Canonical.

  Thanks, Gary
