ACPI failure

[Dan Vratil <progdan@progdansoft.com>]

Hi there,
this mailing list is probably my last chance to get some help. I have MSI 
laptop. It's Windows Vista compatible laptop. But I have problems with ACPI - 
since I use Linux on it.
I'm running Linux on this laptop since 2.6.22. In this version I had problems 
with "crashing" ACPI . But with almost every new version, ACPI has being fixed 
and improved and in 2.6.25 it was working pretty well. Everything was working, 
then, for about a minute ACPI crashed (showing no battery, no AC, temperature 
@ 146 C) and then it just restored and kept running. I haven't found any 
regularity in the crashing, I think it was absolutely random.
Then in one version (i think it was 2.6.25.6, but not sure) ACPI tables were 
updated to be compatible with Windows Vista, but it has broken down my ACPI 
(strange, isn't it? Vista tables not working on Vista compatible notebook), so 
I returned to lower version.
Few days ago I updated to 2.6.26.2. Still same - after some time ACPI crashes, 
but does not restore anymore (untill reboot). There is absolutely nothing 
about it in dmesg and logs.
I've decided to check, if my DSDT is buggy or not. It was. I fixed it. I have 
also compiled kernel with ACPI debug statement enabled. Even with my fixed 
DSDT, ACPI is still broken, but I have some strange errors in dmesg during 
boot:

ACPI: Interpreter enabled
ACPI: (supports S0 S1 S3 S4 S5)
ACPI: Using IOAPIC for interrupt routing
PCI: MCFG configuration 0: base e0000000 segment 0 buses 0 - 255

Full DMESG output i've uploaded here: http://pastebin.com/m1359a16

I'm not ACPI expert, so I have no idea about what this means, or if it's 
important, but I hope, there is someone here who will have an idea and will be 
able to tell me what should I do to fix it.

Thanks for any response

With regards
Dan Vratil
