Can anyone help me? I dont know more what to do..

Since this was caused by linode maintenance, you should probably open a ticket.

Solved, was a issue in /etc/default/locale and a network problema that linode solved.

Test your reboots!

Also, for a zero-downtime method of doing this, you can clone your linode and try booting the clone. This should simulate an unplanned reboot, if I'm not mistaken, although it would cost you one day of your linode cost pro-rated.
