Hi,
this happened while I removed my battery on bootup. Complete dmesg is
attached. Kernel is 2.6.24-rc1-git of yesterday (last commit was
d919fd433b5823d1cf9d0688eb2eec183de9b74c).
Greetings,
Eike

Ok, I found out that it has nothing to do with the actual removal as it seems.
When I start the laptop with battery already detached I get the same error.

It makes the crash go away. But there is something weird going on. Before I
logged into X I did an "cat /proc/acpi/battery/BAT1/*" and it showed the
battery as present with some (random?) values. Now I'm in X and everything
looks fine there (as in "not present").
