dmesg for unexpected shutdown

[Thufir]

After pressing the power button to turn on the pc, it spontaneously 
shutdown after just a moment.  I pressed the button again and it turned 
on fine.  Initially I thought perhaps the powersupply, or something 
similar, broke, but that doesn't fit since it's working fine now.

dmesg output:
