if I can! I have have a problem but i dont know what is culprit. I try to describe it:often it happens alternatively. Shutdown-Reboot-Shutdown-Reboot-Shutdown-Reboot... Sometimes when device reboot I’ll see nokia logo, after that black screen(dark blue) and points of starting OS doesnt appear, Device doesnt load & I must push button for long time to shutdown. After turn on device I see the popup like this "unexpected reboot. Your kernel-power setting is not loaded". I will described only operation with power button & shutdown in popup. I’ll not uses commands in x-term & reboot options
