This is rubbish.
View CommentView CommentDo you have any sources for your claims of kernel panics and hardware failures attributable to ACPI? I don’t think so.
On the other hand, disabling ACPI will drastically increase the heat generated by the whole computer, raising its internal temperature, which is the best-known way to shorten the lifespan of all its internal components, including CPUs, hard drives, VRMs, and fan too, because they will be spinning at full speed all the time (increased speed = increased friction, and therefore wear).

Hi,
There are plenty of complains from old mailing lists. ACPI Support has never been too good in Free Software realm (as far as I know). On servers I really doubt what would be the purpose of just one another piece of memory pre-loaded software, which every now and then makes the server fan to change rotation cycles. Imagine you’re running a webserver and it is very loaded sometimes, and sometimes the load drops, imagine this happens frequently, in situation like this I’m quite sure ACPI will make the fan cool less at points and therefore on high loads it will be easier for server to be overloaded due to overheat. Maybe my logic is wrong somewhere, but this is how I think. Besides that I don’t think disabling ACPI will increate oseverall heat? Why would that be? Maybe you’re right, pls explain why would disabling acpi increase heat?
Regards,

What a misleading and outdated entry!
We’re running thousands (no exaggeration here) of Linux servers with ACPI enabled and at least in the last two years we haven’t have any incident which was ACPI related.
What’s more, if you follow this “tip”, you OS might not function properly as parts of it rely on ACPI.
To quote from http://doc.opensuse.org/products/draft/SLES/SLES-admin_sd_draft/cha.pmanage.html : “Some newer machines (especially SMP systems and AMD64 systems) need ACPI for configuring the hardware correctly. On these machines, disabling ACPI can cause problems.”
And who haven’t got a 64 bit machines, these days?

Hi Walter,
Thanks for the tip. Maybe I was wrong it was my common logic and assumption about ACPI. If I was wrong or misleaded someone. By the way, I don’t use SuSE, so dont know the situation with it. Also I’m not sure SuSE is very good choice for servers.
Thanks again,
Best

Hi!
Do you know that the ACPI logo that you used is Copyright to the Animation Council of the Philippines (ACPI)? We the members of ACPI request that you use a different logo. This brings a negative connotation to our Association. It looks like Tux doesn’t support our Association.
Thank you!

Hi thanks for saying I didn’t know. I removed the logo from Tux. Hope now it is ok.

Hi,
View CommentView CommentI'm running a server with the Ipfire core 67. The network sketch has 4 NICs.There's a situation that is driving me crazy. Two weeks after installation, one the NICs (the blue network segment) deactivates itself. I have tried editing the acpi kernel boot line and what happens is that with acpi=off the NIC doesn't deactivates but the internet conexion is down.with pci=noacpi, noapic and the noapic is the same thing, the Nic deactivates itself leaving the blue clients without conexion. The Ipfire console shows a <<disabling irq #18>> which is the nic that is being deactivated.
How can i disable this acpi option or daemon without interrupting the internet conexion of this blue Nic?
thank you

Hi Willbert,
Try to disable ACPI support on BIOS level and see if it helps. I hope this solves it. Otherwise you can try to also disable any loaded modules in kernel related to ACPI, I guess one of this 2 might solve your situation. Also if you have some embedded sound card / modem or whatever you don’t need on system make sure you disable it from BIOS.
Regards,

Check into locations and concentrate on areas of your current exercise routine training that you just really feel you could utilize help with.
Aim for a higher amount of reps with medium-high intensity weight if
you teach. For each and every individual workout
you need to do, attempt to do some ten or fifteen reps,
resting below one minute in the middle every set.
This leads to lactic acidity to develop within your muscle tissues, helping to make you “notice the shed” while exercising progress.
Should you be looking to build muscle tissue, it is important to try to eat caloric-dense food on the perfect
time. The optimum time to nibble on your heaviest meal through the day is once you
have accomplished your muscle-building exercise program. It is actually at the moment the power needs of your
body are at maximum degrees given that your body needs the nutrition to
fix and build muscle groups. If you consistently try to eat some other calorie-heavy meals every couple of hrs, you can expect to
offer a chance for the body to incorporate much more muscle tissue.
Crank up some songs. Research shows that playing audio you adore when you are
lifting will help you do more reps than not paying attention to any music by any means or not listening to the songs that you prefer.
Furthermore, having headphones might help distract you
against having a discussion with others which will defer your training session.
It is quite vital that you stand properly when doing ranking
workout routines, including overhead presses and squats.
These workout routines call for a form of fitness stance. To
experience this, you ought to stand along with your feet at concerning the size
of your shoulder blades. Then, a bit stage your toes
outward, flex the knees, and arch your spine.
Make sure that your vision are seeking frontward.
A 60 second workout is the maximum span for maximum results.
Beyond 60 minutes, the body commences issuing the stress hormone, cortisol.
Cortisol diminishes your male growth hormone degrees, which just waste materials your efforts to
improving your muscle mass. An excellent approach to making sure you maximize your routines is usually to always keep workout routines at less than one
hour long.
Avoid comparing you to ultimately other folks at the health club.
It can be useful to see others to discover their type, new workout routines, or new kinds of equipment, but immediate comparing is just not valuable.
The reason being everybody has another body type what really works might not work for other people.
Focus on your body extra fat and evaluate it frequently.
Try not to be disheartened if you find not important weight reduction when muscle building,
because your bodyweight might not alter a lot
by using a bodyweight and muscle building regimen.
Your system body fat is actually a much better way of measuring your overall health rather than weight.
Ensure that you are eating the amount of calorie consumption that
your body needs. There are many of on-line calculators that you can use to find out caloric needs dependent on
your goals. Use one or two of the calculators then change your diet plan
accordingly, including the proper levels of carbs, healthy proteins along with other vitamin supplements to construct your own muscles.
Work your own muscles to weakness to get the best is a
result of your workouts. Keep nothing at all around the table.
When finishing some exercise routines, maintain pushing your self
till you are not able to complete yet another force-up or elevate the nightclub yet another time.
You can then begin to use weightier weights and doing less repetitions to boost muscles dimensions.
Making a smart agenda for your muscles developing workouts will keep the muscles increasing and keep
you from injuries. It is recommended that beginner muscle tissue home builders work out only two times
every week, when people that have practical experience
is capable of doing so three times per week.

well..
my laptop (2013) is getting so hot that after a while i get artifacts on the screen… but my fan never goes fullspeed.
after disabeling acpi (centos7) my fan is going fullspeed at times when it is getting hot.
downside is that the fan makes a lot of noise but upside is that i dont have to shut down my laptop to let it cool off.

obviously like your web-site however you have to take a look at the spelling on quite a few of your posts. Several of them are rife with spelling issues and I find it very bothersome to tell the truth on the other hand I'll surely come again again.

Great article,
useful for those who rent dedicated servers with buggy ACPI.
thanks
