    I have just upgraded to Mountain Lion and I sadly have to report that the problem is still here. I triggered it (as usual) by forcing the MB Air to heat up by inserting it in the protective sleeve. As ususal the problem goes away when the sleeve is removed.

    If that's not heat-related:

    then I don't know what it is.

    seriously

     

     

    everyone blast the dust/cathair out of the upper and lower vents of their macbooks and report back

    Aah. we're being serious, then? Note that I've removed the back of the casing to do the vacuuming. It's easy, same procedure as when adding some RAM or whatever, but you need a special screwdriver (iFixIt sells a kit).

    I think it is clear that the problem is related to the temperature.

     

    Dirt, covers, living in a hot place (40 C degrees, 104 F, in my city)... all these are different variables that causes the problem.

     

    Anyway, the kernel_task should not run wild: this raises the temperature of the machine more and more. This is a bug.

     

    If the machine is so hot that it cannot proceed, it should warn the user about the problem and suspend or halt.

    > If the machine is so hot that it cannot proceed, it should warn the user about the problem and suspend or halt.

     

    Fact is that while mine (=fast as it ought to) has been running smoothly after the vacuuming procedures I've explained, it shut down brutally a couple of mornings ago ago, as if some ghost finger had pressed the Power button (I'd just walked away from it). Never ever had that happen before, unless the plug was pulled from a stationary machine (this is a MacBook Pro). Only explanation I came across on the net: overheating.

     

    It hasn't happened since, but I'm puzzled, nonetheless. Maybe same location as you, we're in the midst of a heat wave, relatively speaking, but I manage to keep the ambient temperature in the office at ≈ 27°. Touching the MacBook does feel hot in places, mostly next to the power plug that comes from my Cinema Display. And I must admit that I usually have lots of apps and downloads and streaming and Firefox tabs running simultaneously, but it happened in the morning, shortly after turning it on.

    special screwdriver?  you mean a philips?

  • 83. Re: kernel_task running wild!
    tingotanca Level 1 Level 1 (0 points)

    iFixIt does call it a Phillips, but it looks a bit different to me. Anyhow, it's called PH000, part of the iFix set called 54 Piece Bit Driver Kit, which includes about every bit under the sun (see http://www.ifixit.com)

     

    That's to open up the cases of my two MBPs (2010 and 2011), I wouldn't know about other models.

    lol

     

    dude its an ordinary philips screwdriver

     

    possibly the second most common type of screwdriver on earth

    I'll happily pass your kind words to the person in charge of our workshop, whose chores include the management of screwdrivers. In our company, "dude", we take pride in giving vastly more intelligent people the opportunity to demonstrate their wisdom to worms like ourselves, who crawl about in those barbaric corners of the planet where access to common consumer goods that abound in the Heart of the Great Civilisation is sorely limited.

    This "person in charge" wouldn't happen to be your mom and "our workshop" wouldnt happen to be "your mom's basement" perhaps?

    Just wanted to get back to you guys & gals with what I found. I'm going to call this problem as hardware. I did a complete clean install of 10.7 after upgrading to 10.8.

     

    Once the clean install was finished I opened Ativity Monitor and sure enough the Kernel_task was still using 100% of one of my cores. I will be opening a ticket with Apple GSX and getting my hardware replaced.

     

    I'll let you know if the problem is gone once I get my machine back from Apple.

    I had the same problem with my MBP 13" early 2011 , and thank god it got fixed by disconnecting the battery which was already dead since a month ago due to high temp :(

    Hope this may help anyone in the future
