Latest working kernel version: never worked 100%, last best performance in
2.6.25
Earliest failing kernel version:
Distribution: ArchLinux up-to-date
Hardware Environment: MSI EX600 notebook

Problem Description:
I have MSI EX600 notebook. ACPI here was never working 100%, but since 2.6.22
it has really improved. 2.6.25.7 was the last version, where ACPI worked pretty
good. Sometimes it has "crashed" (no battery, no AC, temperature at 146 C), but
in less then minute it has restored to original values, and kept running for
some time again.
2.6.25.8 came with Windows Vista ACPI tables. This notebook is recommended for
Windows Vista, but paradoxly, this update broke the ACPI. Since this version,
ACPI was running some time, than it crashed leaving nothing in dmesg or logs,
but haven't restored till next reboot. 
I've updated to 2.6.26.2 few days ago and I decided to do something with it.
Here (http://forums.gentoo.org/viewtopic.php?t=122145) I found, how to check,
if my DSDT is buggy. When recompiling, I recieved following warning (seven
times - just different lines):

dsdt.buggy.dsl  5329:             Acquire (MUTE, 0x03E8)
Warning  1103 -  Possible operator timeout is ignored ^

I fixed them (changing all the values in Acquire to 0xFFFF) and recompiled the
DSDT. I also compiled kernel with ACPI debug option enabled. This option
brought me following errors in dmesg:

ACPI Error (evregion-0315): No handler for Region [EC__] (ffff88007f8145e8)
[EmbeddedControl] [20080609]
ACPI Error (exfldio-0291): Region EmbeddedControl(3) has no handler [20080609]

ACPI Error (uteval-0232): Method execution failed
[\_SB_.PCI0.SBRG.EC__.BAT1._STA] (Node ffff88007f815fc0), AE_NOT_EXIST

Full dmesg output (from 2.6.26.2) is here: http://pastebin.com/m1359a16

Bug itself: ACPI crashes without any trace in logs,dmesg or so. No way to find
out why or when.

Steps to reproduce:
Buy MSI EX600 notebook, install kernel 2.6.25.8 or higher and wait.
