    Thanks for all the posts folks. You all just saved me from buying a Rev C MBA. If the problem has gone on this long without an Apple official fix or acknowledgment, then I don't have any confidence in this product. I'll wait for an official fix, or just buy something else.

    I suggest anyone experiencing problems with a MBA that is still under warranty, keep after Apple to fix the issue. Call Customer Relations (1-800-SOS-APPL) if you have to. There obviously has to be an answer to the problem if some units like mine work fine.

    Also, I recommend installing ClickToFlash to save on CPU load when using Flash. It really helps an Air run more efficiently.

    As far as thinking about getting a new one, I suggest going to an Apple Store and running a test like I did on a unit (to see what the kernel task is running) before you leave the store with it.

    Good advice. I'd buy one from the Minneapolis Apple Store, but they won't let me break open the seal and test drive the MBA before buying it. LOL I guess it wouldn't matter though, as some folks seem to have this problem appear out of nowhere after months of use.

    After noticing that my Rev A MBA w/SSD was continuously having issues after about 15min on YouTube I thought I'd check the boards and I match these "kernel_task" symptoms to a "T". I brought my MBA to the Genius Bar today and sure enough, in the well air conditioned Apple Store they could not recreate the issue. They said they would take it in the back over night (maybe two) and run some tests on it. I'll let you know know it goes.

    Please, do not let us with out the answer from them, my back herts avery day since I have to turn a fan so I can work in my MBA
  • XJ-linux Level 1 Level 1 (30 points)
    Well, I just ordered a Rev B MBA 1.86Ghz/128SSD refurb. I'd think that if there were a problem, a refurb that was returned and repaired would have the fix. Doubtful, but worth a shot.

    Congratulations! You will love it. Just work it hard for a few day after you get it to test it good. You can run SystemLoad to get it good and warm.

    Also, if you plan on keeping it over a year, get AppleCare before it's a year old. I bought an AppleCare plan for mine off eBay for $120.00. I just made it under the wire. Warranty was going to expire in 3 days after I received it.

    Let us know how you like it.

    I was just looking at purchasing Applecare from ebay as well. Are those copies legitimate? They are almost $130 cheaper than you pay through Apple. It just sounds too good to be true.

    I bought quite a few and never had a problem. This guy (appleguys) is a Power Seller. I bought my Air plan from him.

    So far so good. Seamless migration via Migration Assistant and running just fine. I've only had the fan up to 6200 when installing Win7x86 and it's '07 Office applications via Parallels 4. It's been quite hot and humid the past two days here in Minnesota (even had a tornado last night) but no issues thus far. Here's to hoping she stays solid.

    Sounds like you got a keeper. Speaking of which, keep those tornados over there in MN. They always seem to drift over here in WI!

    I had the same problem after upgrading to 10.5.8. I had CoolBook controller installed on my mBA and used to work fine. With 10.5.8 upgrade, the cool book controller was disabled. On re-enabling coolbook, my problem seems to have vanished.
  • XJ-linux Level 1 Level 1 (30 points)
    Can anyone suggest some recommended Coolbook settings to start out with?
    Thanks,
    Dave

    I use the default setting and it fixed the kernel_task overloading problem.
  • XJ-linux Level 1 Level 1 (30 points)
    No more overheating with the following CoolBookController.app settings on a Late 2008 1.86Ghz/128GB running OS X 10.5.8:

    798 MHz = 0.9250 V
    1596 MHz = 0.9375 V
    1862 MHz = 0.9500 V
