Loading kdump-initrd after a kernel update fails with "no kdump initial ramdisk found"
This document (7018428) is provided subject to the disclaimer at the end of this document.
After a kernel update and reboot of the system the following message will be seen:
linux-7fro:~ # journalctl -u kdump.service -- Logs begin at Fri 2016-12-30 09:26:00 CET, end at Fri 2016-12-30 09:26:35 CET. -- Dec 30 09:26:02 linux-7fro systemd: Starting Load kdump kernel on startup... Dec 30 09:26:03 linux-7fro load.sh: No kdump initial ramdisk found. Tried to locate /boot/initrd-3.12.67-60.64.21-default-kdump.

linux-7fro:~ # cat /sys/kernel/kexec_crash_loaded
If the result is '1' the kdump kernel has been loaded and all should work as expected.
is started it detected that no initrd<kernel-version>-kdump is available in /boot.
The initrd for the kdump kernel will be built at the same time and will be available when the kdump kernel is started if a crash happens.
The simplest way to test if all is working is to run the following command:
echo c >/proc/sysrq-trigger
This should start the kdump kernel and save the kernel dump of the production kernel.
