There is an issue in 2.6.31 where it will panic (at least that's what I 
think it does, please see more details in 
<https://bugs.launchpad.net/bugs/473876>) when you have it plugged in, 
suspend, un-plug the power cable, and then resume it.

According to <https://bugs.launchpad.net/ubuntu/+source/linux/+bug/467877> 
it has something to do with "event_when_closed_battery", I haven't tested 
it yet though, neither with 2.6.31 nor 2.6.32. Could be beneficial for 
more people to test though.
