It works OK here.

My guess would be that you died here:

list_add_tail(&driver->node, &acpi_bus_drivers);

in acpi_bus_register_driver(). Which means that some _other_ acpi driver
structure on that list is scrogged. Perhaps it was marked __init or
something.

Can you debug it a bit? Maybe print the addresses and names of the drivers
as they get registered in acpi_bus_register_driver() and also print out
acpi_bus_drivers.prev. If we can get the name of the offending driver
we'll be able to find the bug.
