    I can add to this crash with my iMac (mid 2010) as well running Lion.


    I actually use AirDrop a bit so won't revert the .kext.


    Out of interest, I can reproduce this kernel crash everytime I try and copy a film via Home Sharing from my Mac mini to my iMac.  It will crash EVERY time.


    Combining this with the 5.1 to stereo issue with the AppleHDA.kext, Lion is looking like it just needs a few .kext file updates.

    Same problem for me.

    iMac C2D, 3,06GHz, 4GB RAM.

    no problems running 10.6, after the update to Lion Kernel Panics and the log showing problems with the Airport Atheros.


    Switching off the airport saved me so far from new Kernel Panics.


    Using a wired connection to the world at the moment.

    I think we have to wait for 10.7.1

    Hmm.  Don't know if this a related or similar issue to what you all are experiencing.  My Mac Mini 2.4GHz, Intel Core 2 Duo (upgraded to Lion) started to kernel panic in the past couple of days.  It would do so shortly after a apple magic trackpad connected or disconnected overlay appeared on the screen.  I've now switched back to using the Magic Mouse and all appears Ok.


    When I switched back to the trackpad as an experiment, the Kernal Panics started again.

    Also having Kernal Panics. Especially using the web. It seems to stem from when using a web browser. In my case anyway. When I stop using a web browser the KP stop. - iMac 27" 3.2 i3 mid 2010 using Lion.

    Same as everyone else. Cool with Snow Leopard, frequent crashes with Lion.


    Came home from the cottage, had 5 kernel panics in 30 mins yesterday, and finally lost my ****.


    Searched this forum, and found KYAHX - the man!


    Tried Kyahx fix: kext and kext installer ...


    NO MORE KERNEL PANICS! It's now been almost 24 hours, with at least 12 hours of use/downloading, etc.


    Thank you so much Kyahx! 


    I LOVE Lion, but this was driving me insane, and making my iMac unusable!


    Where were you Apple? Never had an Apple product EVER that acted like this. Disappointing since my iMac is a 2010. This should have been better tested!!!

  • J.Arch Level 1 (15 points)

    Kernal Panics too frequently now. Having to do a fresh install of Snow Leopard and downgrade. It's too important as I do my design work on it. From my experience of Lion I will be staying in Snow Leopard. Lion doesn't feel stable and the things they have taken out and changed are too severe. The new Mail is horrible. The iOS app launcher is tacky and pointless. Never used it. Ditching Rosetta is deal breaker. Can't understand why you would throw such a useful thing away. Felt so stripped of personality as it goes probably the worst OS X ever. It seems Apple is going down the route of being so minimal it has no identity. So much for the 1984 commercial.

    I replaced the IO80211Family.kext with version 3.2 from Snow Leopard. Since then no Kernel Panics any more. I copied the one in System/Library/Extensions to my external hard drive and then put the version 3.2 back with Time Machine. It's not a crucial driver for starting the system, so i tried it. And it did the trick.


    Now there's an update for Lion available (10.7.1) and i checked to see if this driver is replaced by an updated one, and that is not the case. I haven't tested putting the OS X Lion version back to see if this update solved the KP's in some other way. But Apple did not issue a new version of this driver with the current update.


    Just to let you know.

    I have the same problem on my new IMAC 27", 8 days - 6 kernel panics , i replaced the IO80211Family.kext and the problem persists, the wifi connection it's unstable, cut several times and then we return a kernel panic.

  • scottreder Level 1 (0 points)

    I am having the same issue with the Magic Trackpad as the cause of kernel panics on a regular basis, both with 10.7 and 10.7.1 on a MacPro5,1. I'm back on wired keyboard & Mighty Mouse as well until this gets resolved.

  • Kyle Alan Hale Level 1 (0 points)

    I can't believe it, but it's true: just crashed again with 10.7.1.  How could they miss this, when it affects such a large subset of their customers?  Or maybe it doesn't, and there's something else at play that's causing it to affect us.

  • albertmoreno Level 1 (0 points)

    I tried to Change the router and the issue is resolved, i hace a Spanish Vodafone Router, now i installed a Conceptronic Acces Point and works properly.

  • Kerracher Level 1 (0 points)

    Using version 3.2 of the IO80211Family.kext file and Kext Utility to install it, resolved all my Kernel Panic issues.

    I can confirm 10.7.1 still has the problems with Kernel Panics unless installing 3.2 of the IO80211Family.kext file.


    10.7.1 has fixed my 5.1 to stereo issues though as AppleHDA.kext has been updated.  Hopefully IO80211Family.kext will be updated in the next OS update.

  • Fascino Level 1 (0 points)

    Kerrachers reply saves me some work. I didn't test 10.7.1 with the newest IO80211Family.kext and i won't replace the version 3.2 i still have installed until a new update.


    Since i replaced the IO80211Family.kext with the 3.2 version everything runs smooth here. No Wifi problems and no Kernel Panics. i'm not touching anything

  • nicolasfromchambery Level 1 (0 points)



    does this could work on an iMac 27'' mid 2010 ?

    could you please give a like to download that file. I am not an expert and could not find it on website.




  • scottreder Level 1 (0 points)

    An update for those with the Bluetooth/Magic Trackpad kernel panic. I updated to 10.7.1, deleted the trackpad and wireless keyboard from the Bluetooth System Preferences Pane, ran the Onyx "Automation" tab with almost everything selected (particularly kernel cache), re-paired my trackpad & keyboard and have been stable for a couple of days now. I'm hoping that this holds up...
