/var/log/messages output

The kernel did lockup again, but as it a was over the weekend, I did not catch 
it and I had to power cycle the machine. I have attached the outpot of
/var/log/messages. Is there anything else I can retrieve after rebooting the
machine?

I tried 
  journalctl -axb -1
but get
  Failed to look up boot -1: Cannot assign requested address

kernel:  kernel-default-3.11.10-29.1.x86_64
systemd: systemd-208-35.1.x86_64
