acpidump of dell vostro 3350
I have a Dell Vostro 3350 that I have been using for almost one year, but the
laptop got a big problem of auto-shutdown from time to time. The problem was
ACPI reports critical temperature even though the output of sensors command
says otherwise. I had tried Fedora 15, Fedora 16, CentOS 6.2, Ubuntu 11.10 and
Ubuntu 12.04-beta2 and many version of kernels, but they all exhibited the same
problem. If I use dual display, the auto-shutdown can be triggered within 5
minutes. If I don't use dual display, the auto-shutdown may take some time
before it is triggered. I had enabled ACPI debug in the kernel, but the output
is too verbose and I don't understand ACPI well enough to know what's the cause
of the problem. Therefore, I would like to ask for your help on this matter.
The following is the syslog output from the kernel:

Do note that I don't use any proprietary kernel module and I added dump_stack
call to trace the event.
In addition to that, if I comment out orderly_poweroff
(drivers/thermal/thermal_sys.c:1066), the system will not shutdown when this
bug occurs. However, it will later cause an abrupt poweroff.
I'll appreciate if someone can give a pointer or two.
