dmesg before hang

When booting with DPM enabled the machine hard hangs when switching from AC to
battery power or when booting without AC connected as soon as GDM starts.

I can't reach it via ssh after the hang, so only dmesg before hang provided.
Kernel is 3.12-rc2 with agd5f/linux/drm-fixes-3.12 merged in.</pre>
