Title:
kdump-config status - not ready to kdump with v4.18 kernel

Status in linux package in Ubuntu:
Triaged
Status in linux source package in Cosmic:
Triaged

Bug description:
As part of the makedumpfile autopkgtest, a test is done to make sure one can dump the kernel.
The test executes

$ kdump-config status

and expects to find that it is ready to kdump, however it is not.

The check fails at:
$ cat /sys/kernel/kexec_crash_loaded

Previously it was 1, but now it is 0.

Is this intentional? Do we need to change something in makedumpfile?
Or is something missing in the kernel?
