Hi,=20
On my laptop which is not SMP , is a Intel Centrino 1.7Mhz , I have a
little stranger problem my lid button (backlight) doesn't work with
_DOS=3D0 after load Hal service and on first boot.=20
Like _DOS=3D0 on some laptop crash on lid close.=20

The report #6001 , made by other S=E9rgio (not me), which complains on
system freeze when _DOS=3D1 and on switching display.=20
Switching display for him means on switching to CTR or to monitor with
fn+ f4. With acpi=3Doff don't freeze because that have the event , and
with acpi on, freeze , so IMHO, this is a problem probably not related
with _DOS value, S=E9rgio Luis , in last comment
( http://bugzilla.kernel.org/show_bug.cgi?id=3D6001#c51 ) wrote with
updated kernel freeze in the 2 cases.=20

But this report introduce a patch in main kernel that change _DOS from 1
to 0 , which I think at least should be reverted.

I'd love learn more about this switches , if someone can help me with
some tip , many thanks,
