ASUS M6800N: problem when removing 'ac' module

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hello,

I'm on '2.6.5-rc1 + ACPI DSDT in initrd + eciadsl USB patch' and I get this message when I 'rmmod ac' or 'modprobe -r ac':
=====

and the AC state in the 'GNOME Battery Applet' isn't updated (it still shows I'm on AC mode).

Please let me know if I should post in the kernel bug database.

Thx, bye,

Please take care that it doesn't happen with other modules (like 'ehci_hcd' or 'joydev').

Solutions?

Hello,

- - I don't have oops on kernel 2.6.4 + ACPI 20040311

- - I've oops on 2.6.5-rc1 (no ACPI patches) and 2.6.5-rc2 (no ACPI patches)

Maybe it should help...

Thx, bye,
