Kernel doesn't log ACPI events: ACPI module or Bios corruptions

Question

Well, this is very strange and i dunno where to look at to solve this:
My new NP530U3C (Samusung ultrabook)is running Arch and i'm currently using acpid to trigger the acpi events couse i have no DE (fluxbox).
I can't understand the way my kernel and acpid log the LID event:
Kernel.log
Oct 6 20:06:46 localhost kernel: [ 2.105259] ACPI: Lid Switch [LID0]
Oct 6 20:44:31 localhost kernel: [ 2.111136] ACPI: Lid Switch [LID0]
Oct 6 23:03:18 localhost kernel: [ 2.111244] ACPI: Lid Switch [LID0]
Oct 6 23:17:14 localhost kernel: [ 2.088524] ACPI: Lid Switch [LID0]

Oct 6 23:27:28 localhost logger: LID opened
Oct 6 23:33:40 localhost logger: LID closed
Oct 6 23:33:48 localhost logger: LID opened
When i close the lid, i have to wait 10 sec approx to trigger the LID close event and start the suspend action!
on wakeup i don't know because my samsung can wakeup only with the power button (no lid in wakeup events).
So somebody can enlighten me?
*EDIT <-----
I can summarize it is a corruption of the Bios/ACPI module that affect this laptop after a certain suspentions circle (I mean not every first suspentions).
I would like to debug in a better way but i have no instruments to investigate:
If someone can point me to a way to debug this stuff like Bios corruptions and/or Kernel module failure...
Any advide is appreciated

Answer 1

well, is a samsung ultrabook! i'm doing some m ore tests and still 10 sec delayed!
a note:
when the kernel log the LID state i can suspend instantly after i really close the LID.
after a reboot, and halt/start thigs doesn't changes....
The kernel logger resume after some reboots or *resetting* (using a needle to click a button above the laptop close to the battery) the laptop <-- this method was whrote somewhere and i tried it, and solved sometinms the issue for 2/3 days.
is starnge because it appears without any regularity, but i'm not so pro and is difficult for me to figure out what can trigger the event!
EDIT
Oct 7 00:21:58 localhost kernel: [ 686.653890] psmouse serio1: Touchpad at isa0060/serio1/input0 lost sync at byte 6
Oct 7 00:21:59 localhost kernel: [ 686.668774] psmouse serio1: Touchpad at isa0060/serio1/input0 - driver resynced.
dunno if is important, but after a resume from suspend, i got this messege. i thought it was only after it (like a little error in the resume hooks) but no i'm noticing it in  the messages.log every how
