Hi Chao,
On my F21 laptop I tried to start kdump service "systemctl start kdump"
and it failed. I tried to figure out what's wrong and did "systemctl
status kdump" but I don't see any messages there.
[vgoyal@localhost ~]$ systemctl status kdump.service

Actually it works for me:
[chaowang@localhost ~]$ systemctl status kdump.service

When I ran "kdumpctl start" manually, It showed that no memory is
reserved.
I think this message should go to journal so that systemd can show it.
I am wondering what's the problem here.
What does your /etc/systemd/journald.conf look like?
What does "journalctl -b -u kdump" give you?
What about other services? Do their logs get lost too?
Thanks
