For those of you with a Samsung laptop showing this problem, please see
this issue:

           https://bugs.launchpad.net/ubuntu/+source/acpi/+bug/971061

in particular my last two posts.

I think a kernel patch can be made to flush the events from the embedded
controller, at resume, in the same way that I do it with my C program
that I attached to that issue for Samsung laptops (and maybe others with
the problem). TL;DR: If the events don't get flushed (queried), the GPE
of the EC is never triggered again (chicken and egg situation), my
little program queries the events and "unstucks" the EC immediatly.

Title:
  /proc/acpi/button/lid/*/state always says "open"

Status in “linux” package in Ubuntu:
  Won't Fix
Status in “linux-source-2.6.20” package in Ubuntu:

Bug description:
  My laptop is an HP Pavilion dv4000.  I'm running up-to-date Feisty.

  Regardless of whether my laptop lid is open or closed, I always get
  this:

  root@peace:/etc/acpi# cat /proc/acpi/button/lid/*/state
  state:      open

  This would explain why I can suspend the laptop using Gnome's power
  management menu, but why it doesn't do it when I close the lid.  (I
  have specified under power management preferences that it's to suspend
  when I close the lid.)

  I know that at some level the lid switch works because when I press it
  the screen backlight turns off (although I can still faintly see that
  the display is still live).

  There was one hint of the issue in this email:
     http://lists.opensuse.org/opensuse-mobile/2007-02/msg00016.html

  Here's a Ubuntu bug that seems similar, but got rejected:
     https://launchpad.net/ubuntu/+source/kernel-package/+bug/16662

  My bug is different than this one:
     https://launchpad.net/ubuntu/+source/linux-source-2.6.15/+bug/34389
  because my laptop state is *always* reported as open.

  I've attached the output of dmesg and dmidecode.
