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?

--- Comment #3 from Lucas Stach d...@lynxeye.de ---
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.
