IMHO in case of OSS it is the problem because it lacks a function fundamental for home users and I imagine home users are the largest group using sound on linux.

Or perhaps point to a nice document about what should a general device driver do to support suspend?
A big thank you in advance.
pm-utils can be thought of as a collection of shell scripts that wrap the kernel mode suspend/resume with the various hacks. These hacks are needed to work around bugs in drivers and subsystems that are not yet aware of suspend. It is easily extensible by putting custom hooks into a directory, which can either be done by the system administrator or those hooks can be part of a package, especially if this package needs special attention during a system suspend or power state transition.
A common Linux problem is missing ACPI functionality (fans not running, screens not turning off when the lid is closed, etc.) https://wiki.archlinux.org/index.php/DSDT
$ acpi -V | grep critical
Thermal 0: trip point 0 switches to mode critical at temperature 95.0 degrees C
CAUTION: To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching an unpainted metal surface, such as the back panel on the computer.
Cleaning a System
One of the most important operations in a good preventive maintenance program is regular and thorough cleaning of the system inside and out. Unlike desktop systems, laptop systems don't have air flowing through all their parts, so they are more immune to dust internally and normally don't have to be disassembled for cleaning. Laptops do, however, usually have fans that draw air through cooling ducts with heatsinks mounted inside them. Dust buildup in these cooling passages can be a problem because the dust acts as a thermal insulator, which prevents proper cooling. Excessive heat shortens the life of components and adds to the thermal stresses caused by greater temperature changes between the system's full power and sleep/power-off states. Additionally, the dust can contain conductive elements that can cause partial short circuits in a system. Other elements in dust and dirt can accelerate corrosion of electrical contacts, resulting in improper connections. Regularly blowing out any dust and debris from the cooling passages (through the vents) will benefit that system in the long run...
Cigarette smoke contains chemicals that can conduct electricity and cause corrosion of computer parts. The smoke residue can infiltrate the entire system, causing corrosion and contamination of electrical contacts and sensitive components, such as floppy drive read/write heads and optical drive lens assemblies. You should avoid smoking near computer equipment and encourage your company to develop and enforce a similar policy. http://www.quepublishing.com/articles/a ... x?p=102215
Hi. I have the problem with the temperature. The notebook gets too hot. I have read and tried everything in the web but the problem persist. The sad part is that the same notebook with windows has much less temperature.
Sometimes the notebook turn off by itself due a high temperature. Almost daily.
I'll put all the informacion of my pc and hopefully you can help me because i dont know what to do.
Video Intel HD Graphics
Intel(R) Core(TM) i3 CPU M 380 @ 2.53GHz
3Gb de RAM
Kernel Linux 3.2.5-1-ARCH
Normally the temperature is over 70. When i decompress a big zip or I have 3 flash videos open the temperature rises to over 80
Please please please help me!
[Arch Linux] Lenovo Ideapad U460 overheats very easily and loud fan
My Lenovo Ideapad U460 overheats even when I have 10% CPU usage while my fan is often on and very loud even while I'm using very low resources. Any suggestions?
I've been having this issue for a long time and just figured it's just how this laptop performs.
arch + samsung r540 = CPU overheating
Today 13:21:23 (2012.02.27)
Some time ago I installed arch on my laptop (samsung r540), and I've been experiencing problems with overheating ever since.
Every time I need to do something that requires CPU power (in my case mainly compiling/installing form aur) my cpu temp spikes instantly and laptop shuts down. This is quite frustrating, since it's preventing me form doing any work.
...the temperature spikes instantly to 90C and the system shuts down. Same thing if I try to compile something, encode/convert audio/video or do anything that requires cpu usage.
Before shutdown I see message about throttling down my cpu speed because temperature is above threshold, then I get message about critical CPU temp and system shut downs.
I hear the cpu vent going up when the temperature goes above 80C [!!!]
A variety of desires for collective benefit coupled with apparently irrational strategies to attain those desires have attracted the label cargo cult. Such labeling occasionally evokes tragedy, playing upon the melancholy future of unfulfilled desire. But most often, cargo-cult labeling highlights an irrationality of practice rather than sorry futures.

You see, many of the troubles going on in the world right now are being supervised by people with very good intentions whose attempts are to keep things in order, to clean things up, to forbid this, and to prevent that. The more we try to put everything to rights, the more we make fantastic messes. Maybe that is the way it has got to be. Maybe I should not say anything at all about the folly of trying to put things to right but simply, on the principle of Blake, let the fool persist in his folly so that he will become wise.
Fan Always Runs Or Laptop Overheats And Shuts Itself Off
Warning! Before Disassembling Laptop always unplug power and remove the battery.
Laptops that shut down without warning are often experiencing overheating issues. Overheating may be a symptom of age, of clogged ventilation or impending failure, but it can also result from simply using the laptop in a bad location. Before you try to take the laptop apart to look for problems, it pays to patiently troubleshoot the symptoms and see if an easy fix is possible...

[Arch Linux] laptop going to meltdown [2012-05-31]
I've only recently installed arch but i worked fine until the last update I did.
Since then my cooling fan hasn't been comming on after boot (it starts untils arch boots).
I've looked into it and found this :
Adapter: Virtual device
temp1: +81.0°C (crit = +120.0°C)
temp2: +81.0°C (crit = +120.0°C)
Adapter: ISA adapter
Core 0: +79.0°C (high = +100.0°C, crit = +100.0°C)
Core 1: +79.0°C (high = +100.0°C, crit = +100.0°C)
Is there any way to bring the crit temperature down please.
Thanks for any help you can offer.
ps:if it's of any importance I'm on a HP pavillion dv2500.
[Arch Linux] Poweroff doesn't work with acpi=off [2012-06-15]
shutdown -hP now, poweroff etc results in halt but not poweroff. I have to press the power button (lightly) for it to finally power off.
All the daemons stops, then it says
> POWER OFF
[(number)] System halted.
Then it doesn't turn off. It works without the "acpi=off", but then the computer freezes when the fan turns on.
Reboot works fine.

acpi=oldboot Deactivates the ACPI system almost completely; only the components required for the boot process will be used.
