Kernel oops (2.6.24) while booting with battery inserted

Hi List,

I encountered kernel oops (Ubuntu 2.6.24-12) while booting with battery inserted.
Some workaround are acpi=off, avoiding loading battery.ko or putting battery away.

Any idea ?

dmesg and dsdt as attachments.

Why do you need:
acpi_fake_ecdt
parameter? This does not even exist (anymore? I searched 2.6.25).

Quoted 1 line

I expect removing the line:

        acpi_bus_generate_netlink_event(device->pnp.device_class,
                                        device->dev.bus_id, event,
                                        acpi_battery_present(battery));

in battery.c makes the machine work or at least go a bit further?

Could it be that you compiled in ACPI modules and that:
fs_initcall(acpi_event_init);
in drivers/acpi/event.c
has not been called and initialized the netlink acpi stuff, but battery has already tried to send an event?

acpi_event_init should have been called already... I still think it has to do with the netlink event. As it is rather early, maybe because of that. Does it work for you if you load the battery module later?

Can you open a bugreport on bugzilla.kernel.org, add .config and dmesg/acpidump you already sent and add me to CC.

Thanks,

Thomas
