(not so) smart battery manager
Today my mac hung when it ran out of battery. Well, it not actually hung in the sense freeze, rather the applications refused to work. I could switch between apps, some worked, but some showed me the spinning beachball of death. The symptoms where just as if you leave the network without unmounting a network volume.
After a while of patient waiting, I force-quitted most of the apps, but I had to use the power switch to really finish it...
kernel[0]: SmartBatteryManager: retrying command 0x0f; retry due to absurd value _zero_
Sure, my battery showed to be empty, but still the computer worked. The sensors reported a completely empty battery: a condition under which the computer normally wouldn't work anymore. Probably the software ran into a never-meant-to-reach bit of code.
Suprisingly I found myself to be (according to google) the first person to have noticed this problem.
