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.

possible fix

Does this patch help?  Seems like maybe your system isn't getting ac events
properly.  Can you attach the dmesg output of this patch?

Yes, the patch fixes the immediate lockup. But it seems your analysis on why it
fails isn't correct as I can now see your printks toggling between AC and DC
when plugging in/out external power.

Does this patch also fix the problem?
