Hi, 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=0 after load Hal service and on first boot. Like _DOS=0 on some laptop crash on lid close. The report #6001 , made by other Sérgio (not me), which complains on system freeze when _DOS=1 and on switching display. Switching display for him means on switching to CTR or to monitor with fn+ f4. With acpi=off 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, Sérgio Luis , in last comment ( http://bugzilla.kernel.org/show_bug.cgi?id=6001#c51 ) wrote with updated kernel freeze in the 2 cases. 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, On Tue, 2008-11-11 at 02:05 +0000, Matthew Garrett wrote: > On Tue, Nov 11, 2008 at 09:59:38AM +0800, Zhang Rui wrote: > > > oops. sorry, I mean system crashes on lid close if _DOS=0 on some UP > > platform. > > Oh, ugh.
