I am trying to diagnose whats in syslogs at time of hang

Here is my ongoing analysis

Till now i have not found solution and problem.

It can be hardware issue
It can be a software issue

I am grouping my syslogs messages at hang time in different posts here on blog and corresponding steps in took.

Sep 14 10:28:55 nanak-P570WM kernel: [ 4855.198902] ACPI: EC: GPE storm detected(9 GPEs), transactions will use polling mode

Read on net about what is GPE storm  , it can be a hardware issue. One of the solution suggested here was to add boot parameter which can tell apci that this is linux machine.

I did following

#Commented as per http://forums.linuxmint.com/viewtopic.php?f=42&t=56323
#GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux"

sudo gedit /etc/default/grub

sudo update-grub

Lets see how it goes

Update : It has been more than 24 hours since i had the same issue. Seems things are working with that grub conf change about acpi_osi
Last error i had on 13 Sept 2013 when i changed this setting.
