juanmanuel,
No matter who found the latest/better solution, you are truly a hero.
After reading all the associated bug reports, I decided to use your script
because I don't know how to compile the kernel, and I presume I would have to
redo it every time the kernel got an update.
My laptop model
Breaking News!
A fix in the form of a kernel patch has now been posted to the linux-
acpi and linux-kernel mailing list:
[PATCH v2] ACPI / EC: Clear stale EC events on Samsung systems
http://marc.info/?l=linux-acpim=139359680828880w=2
That kernel patch was made by Kieran Clancy
I also have a Samsung NP-A530U3C-A01UK laptop that exhibits the same
behaviour. Since applying the fix from juanmanul all is now well.
Many thanks juanmanual for identifying the cause for this long running
issue and for working diligently to find the fix.

UPDATED v2: Safer because it obtains the EC ports automatically from
/proc/ioports, and it micro-pauses between queries, so that the EC returns each
event only once. This replaces the little program in #3.
This is the program I made, that unstucks the computer so that it can send

Christopher: you changed my description of the bug, and in doing so,
confused the two different ways to force the issue to show up. You
listed the second way as a fourth item of the first way, when it is a
different way.
Take a look at the original description.
