[arch-general] How to show (kernel) messages by journalctl?

[Ralf Mardorf]

Hi,

yesterday I rebooted at 17:51 from linux 3.11.4-1 to linux-rt
3.10.14_rt9-1 and then shut down at 17:55.

How can I get log data, kernel messages of this startup?

This is all I get:

[rocketmouse at archlinux ~]$ journalctl -a --since "2013-10-12 17:50:00" --until "2013-10-12 18:00:00"
-- Logs begin at Wed 2013-08-28 22:06:09 CEST, end at Sat 2013-10-12 20:36:06 CEST. --
Oct 12 17:51:10 archlinux systemd[579]: Stopping Default.
[rocketmouse at archlinux ~]$

A log in for rt kernels 3.10.x doesn't work on my machine, rt kernels
3.8.x don't cause this issue. During shutdown and startup there were
much more messages, than just "Oct 12 17:51:10 archlinux systemd[579]:
Stopping Default."

[rocketmouse at archlinux ~]$ journalctl -k
-- Logs begin at Wed 2013-08-28 22:06:09 CEST, end at Sat 2013-10-12 20:36:06 CEST. --

JFTR there are no .xsession-errors.old for the attempt to log in.

Regards,
Ralf
