[ACPI] insmod/rmmod bug?

[Cagle, J. (ISS-Houston) <joh...@hp...>]

There appears to be a bug in acpi_bus_unregister_driver().  In the case
of the button driver, it's not calling acpi_button_remove() when I
"rmmod button".  This causes problems when I attempt to "insmod button"
again.

Here's the log showing the "Error installing notify handler" that occurs
the second time I do "insmod button":

 stormin:/proc/acpi # insmod button
 Using /lib/modules/2.4.20-rc1/kernel/drivers/acpi/button.o

 stormin:/proc/acpi # dmesg -c
 ACPI: Power Button (CM) [PBTN]

 stormin:/proc/acpi # rmmod button

 stormin:/proc/acpi # dmesg -c

 stormin:/proc/acpi # insmod button
 Using /lib/modules/2.4.20-rc1/kernel/drivers/acpi/button.o

 stormin:/proc/acpi # dmesg -c
 acpi_button-0359 [-40] acpi_button_add       : Error installing notify
handler

Has anyone else seen this problem?  I'm using the latest linux-2.4-acpi
kernel from bitkeeper.

Regards,
John
