In this bugreport
(http://www.mail-archive.com/acpi-bugzilla@xxxxxxxxxxxxxxxxxxxxx/msg03861.html)
about a different laptop the following is said about this laptop.
ACPI: Looking for DSDT ... not found!
This message is not in the kernel.org kernel source tree, either
as of 2.6.15, or as of 2.6.18. While your system seems to have
plenty of other problems, ACPI did find the DSDT and it is running
normally.
I expect this message comes from the "initrd DSDT override patch"
that some distributions, such as SuSE and Ubuntu tend to add to
the kernel as their "value add" -- complain to them.
I do have the impression that ACPI is partially enabled: events such as
plugging out the adapter, closing the lid, ... are detected. Others
again arent (temperature does not work, etc). Furthermore, I do have a
non-empty /proc/acpi/dsdt.
Following this DSDT lead, I found the following page:
http://forums.gentoo.org/viewtopic.php?t=122145 and did the following
actions:
$ sudo cat /proc/acpi/dsdt > dsdt.dat
$ iasl -d dsdt.dat

So apparently my DSDT contains no errors and a few warnings. Maybe they
are causing the few functionalities not working?
Other leads I can pursue? How could this be related to the hpet=disable
kernel param I need to give before booting?
Thanks for your help!

This should be a starting point, without DSDT ACPI will be disabled on your machine:

Before, DSDT was listed among other tables, so it probably exists, but has wrong checksum
or it may be some huge problem with Ubuntu kernel...

Dear ACPI list,
further finding with my notebook:
A lot works out of the box with Ubuntu edgy: suspend, wireless, card
reader, ..., BUT:
- There is still the hpet issue, which - I think - screws up my thermal
readings (is that possible).
- The reason I'm thinking this is that every ACPI related thing works
well enough, except for fan control and temperature reading. Since my
fan is on all the time, this reduces my battery life drastically.
- Since these issues were happening with similar models (MSI S271 also
has this Ati chipset), and BIOS fixes resolved these issues, I am
planning to ask MSI for a BIOS upgrade.
- What I would love is someone who wants to look into this, so I can
present a reasonable case at MSI and make them release a fix for my
problems.
- Or, when the problem is the ACPI linux stuff, I want to look into how
fixing this. Again, help is appreciated!

Dear acpi list,
I bought me a brand new laptop, MSI S420 based on the MS-141214
barebone):
http://www.msicomputer.com/NB/product_spec.asp?model=MS-141214.
Of course, and too bad, not everything is supported in terms of acpi
and I am eager to look into this problem. I will enumerate on my
issues and observations here, hoping some willing ear would lend a
helping hand.
I am running ubuntu edgy beta now which runs the 2.6.17-10 kernel and
I have seen the same issues in ubuntu dapper which has a 2.6.15 kernel.
1. When booting the machine in a default configuration, it hangs
(kernel does not respond to any sysrq key combinations) after the
following lines:
using HPET for base-timer
using HPET for gettimeofday
Detected 2000.186 MHz processor
Using hpet for high-res timesource.
Playing with some kernel parameters, I notice the following behaviour:
no effects with pci=noacpi, acpi=force,noapic, nohpet, ...
What does work is: acpi=off but then I have no acpi at all, another
option I discovered is hpet=disable, which enables some of the acpi
functionalities.
2. with the hpet=disable parameter, I can see battery state, but
remainng time is calculated incorrectly (always giving the same amount
of minutes), plugging in and out the adapter is recognized however.
Reading temperature does not work as he always gives the constant heat
of 75 degrees. Cpu frequency scaling does not work.
3. output of dmesg | grep ACPI and dmesg are in attachment.
4. While booting the kernel, but apparently before putting things in
the kernel log, some messages appear (three), among which something
about a BIOS bug. They flash away too fast for me to write them down,
so a way of capturing these is appreciated.
5. Would fixing the DSDT (of which I read some stuff here and there)
be helpful in my case? Is it dangerous? Is there someone to walk me
through it?
6. My BIOS is v1.01 and is definitely the current version as it is a
very new laptop in general.
Any help is greatly appreciated!
