    I was with a friend today, and his MacBook[2,1] kernel panicked. This is the first one I've ever seen with my own eyes. He says it happens every so often, and I'm determined to find out what the cause is. He says it happens every month or so, and he has reinstalled the OS several times before. Here's a log of the kernel panic:

    Are there any clues that someone could translate?

    Thanks.

    A program like Azureus overloaded the Aiport buffer and crashed the machine.

    Something like that, been a reoccurring problem for Leopard.

    Some got it with Azureus, others with non Apple base stations.

    For the people that kept on using Azureus, they just plugged into an ethernet hub.

    ---

    Were some notes where turning off IPv6 worked for some people, and if you look there are a lot of people that had hoped 10.5.5 fixed the Airport issues.

    Well... He said it happened the first week he got it. But a few months ago, his system started crashing so that it wouldn't boot, and he would have to reinstall the OS.

    I know he uses the camera a lot, and that causes his temperatures to stay around 85˚C. He keeps it like that most of the time he's using it. My guess was that it was overheating. I told him to lay off of the camera for a while, and he says it hasn't crashed since.

    But now that he's KPing again... I'm not sure whether to attribute it to permanent CPU damage or if it's whatever happened since that first week he had it (he's had it for a little over a year now).

    He does to limewire... But I'm pretty sure not Azuereus. And what do you mean by "overloaded the airport buffer?" All he had open was Safari where he was doing some online homework.

    Also, he's running Tiger, not Leopard.

    After that back story it sounds like it's time to use the warranty to get the hardware fixed.

    There's the problem if the macbook is the late 2006 model. The one that introduced 802.11n with the "enabler" patch.
    If it is install Leopard with all updates,firmware updates, airport updates.. You get the idea.

    I can almost guarantee you that problem will go away.

    If it's the early 2006 without 802.11n I'd venture to guess bad drivers or possibly hardware. Have you run any extensive tests on it?

    Still happens in Tiger v10+, there is a list of various things to try to get around it, including using the Airport Drivers from a version prior to 10.4.10

    Should have said it was like a buffer overflow, but it isn't, happens more often when the connection was running full, or when a certain call was made -- aka, click here and boom.

    It's a model from 2007, definitely, but I'm not sure what month. He got it in August of 2007.

    I'll see if he's up-to-date with system updates.

    Would there be a fix for that? It has never ever happened to me since I've had my MacBook (June 2007). But then again, I take extra good care of mine (I have a much above average computer background).

    Because Leopard came out in October of 2007, which is 2 months after he got his laptop.

    Leopard has been tried on his system before, but it crashed and ruined the install, causing him to have to reinstall. He doesn't own Leopard, so he went back to his Tiger.
