Sorry, but I think this bug should be fixed with kdump-tools?

When will the new package be available to Xenial,  please?

Thanks.

This seems to be a timing issue between network coming up and kdump-tools 
service
trying to access the remote target with ssh because when I get into emergency 
shell
after failure, this is what I get to see..

[FAILED] Failed to start Kernel crash dump capture service.
See 'systemctl status kdump-tools.service' for details.
Welcome to emergency mode! After logging in, type "journalctl -xb" to view
system logs, "systemctl reboot" to reboot, "systemctl default" or ^D to
try again to boot into default mode.

Most importantly, ssh command to create dir on remote target succeeds
while that is what has failed leading to the below error message in the
first place

"Starting kdump-tools: ssh: connect to host 10.33.31.113 port 22:
Network is unreachable"

Looking into ways to fix that up.

Thanks
Hari
