Hi,

The crashkernel parameter is added when the "linux-crashdump"
metapackage is install.

linux-crashdump depends on kdump-tools which in turns depends on kexec-
tools.

Maybe this should be adapted to z as I don't know how the  linux kernel
is brought in and linux-crashdump is a metapackage of the linux kernel
package.

Kind regards,

...Louis

  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
