Kernel Panic in Lion

Question

Hi!It has been 24 hours now since I&#x27;ve installed Lion on my iMac. Previously with Snow Leopard everything worked smoothly but now every 30 min and sometimes less than that I get kernel panics that keep me from using my computer.This is the report generated after the panic. Can anyone please help me figure out what&#x27;s going on?Thanks in advanceInterval Since Last Panic Report:  6647 secPanics Since Last Report:          4Anonymous UUID:

Hi ! I am having the exact same problem than you and have been suggested to have a look at this : http://www.thexlab.com/faqs/kernelpanics.htmlUnfortunately, I can&#x27;t read the log, but I hope that this link will help in the mean time.

I&#x27;m getting the same problem after upgrading to Lion as well:      Kernel Extensions in backtrace:         com.apple.driver.AirPort.Atheros40(500.55.5)[01000ACB-C064-3F42-820F-BDE2008267 25]@0xffffff7f80e6e000-&gt;0xffffff7f80fadfff            dependency: com.apple.iokit.IOPCIFamily(2.6.5)[95ABB490-3AB5-3D5E-9C21-67089A9AE6A1]@0xffff ff7f80821000            dependency: com.apple.iokit.IO80211Family(400.40)[78A58272-2170-3068-9C63-88301C99C406]@0xf fffff7f80e36000            dependency: com.apple.iokit.IONetworkingFamily(2.0)[59A00F6B-3710-3E07-9921-70C45782FF8C]@0 xffffff7f8091c000Looks like it&#x27;s associated with AirPort, and I&#x27;ve noticed it happening in proximity to me initiating a few downloads from the web. No clue how to fix it, though.

I have the very same problem on an iMac 21.5 middle 2010. If I turn Airport off, everything is ok but if I try to turn it on, I have a kernel panic in a matter of minutes.Please fix this! It&#x27;s a shame!!!!

h3yaz · Answer

say it ain&#x27;t so ... The only I can have network connectio is via WiFi so shutting it down is not really an option..

Vincenzo Acinapura · Answer

Yes it&#x27;s true, I&#x27;m avoiding the update from my home computer because of this problem. I have a cable connection at work and i can turn off airport, but a fix is needed! Also my collegague have the very same issue (same machine, same hardware, very similar software). Every time we turn Airport on, we have a freeze.

h3yaz · Answer

mine works and when it freezes it doesnt seem to follow a pattern. its just random. sometimes every 5 minutes sometimes it can hold up to 4 or 5 hours

Vincenzo Acinapura · Answer

Yes, but it is only a matter of time. We tested this behaviour on two different machines and we realized that if we turn on the Airport, before or after we HAVE a kernel panic. For example, this morning I worked with airport enabled for a couple of hours and then BANG. Kernel Panic. After that, I turned off and the computer was ok from 11:00 am till 19:00.

I&#x27;ve been able to track it down to traffic,  I was fine on a slow DSL connection which was much slower then the WiFi channel but now that I&#x27;ve moved to Fiber it can&#x27;t handle the extra traffic I get panics anytime I try to download a large file or have to many connections open.  This is a serious issue, I can&#x27;t get updates, there&#x27;s no way to slow down the connection. This issue has been around since developer preview 2 .I should note that this is only effecting my Imac 21" 3ghz,  my MacBook Pro (late 2008) doesn&#x27;t have this problem, although it crashes after waking up from a long sleep... ugh

I am having the same problem with my mid2010 iMac. Someone needs to reassure me, this is going to be fixed, right ?

Vincenzo Acinapura · Answer

I doubt someone at Apple is actually reading our thread... the only thing we can do imho is send some crash reports. How can they release a product without proper testing?

msours · Answer

I&#x27;ve been sending them in for about a month, it can&#x27;t go on to much longer before I downgrade. I may call customer support and see what they have to offer (100 feet of ether cable would be nice..) lol

h3yaz · Answer

So I had to go buy an Ethernet cable. You see I use my iMac for work so I couldn&#x27;t get kernel panics every 15 min in the middle of conference calls with clients just to give an example. So far lion as cost me 24,99€+18€ (Ethernet cable - one I have absolutely no to use when everything works as it should)I admit, I have more patience with apple&#x27;s mistakes. If it was some other brand I would, by now, taking other actions. But you see Apple, the promise you make us is: It just works. And usually it does. But you broke your promise on this one and with something so simple and basic as wifi. I&#x27;ll continue to buy your stuff and watching keynotes with more enthusiasm than I watch the FIFA world cup final. But next time I have to be your ambassador with my friends my words won&#x27;t come as easy as they did 1 week ago. For now I just ask you to be as quick as you can possibly be dealing with this issue that affects not only me but many others.

msours · Answer

For comparison reasons only is anyone running with out security on the router? I&#x27;m running n/g/b mixed mode,  20/40 mode, WPA2-PSK with AES cipher.  Its a Trendnet TEW-639GR.Mark

antrozous · Answer

This just might be a coincidence, it might be too early to deduce anything or it might be completely irrelevant, but after doing another clean install of Lion I haven&#x27;t encountered this problem, yet. It&#x27;s been about 24hours now and a day of normal use of my iMac. I may have to edit this post in a few hours to say I had a kernel panic, but as of today, I didn&#x27;t have any, while working exclusively with my wifi, when i&#x27;d get at least 10 in a day after my first installation of Lion. Again, it&#x27;s just an observation and it might not mean anything.

Sparpook · Answer

I am having exactly the same problem!  Kernal Panic ever 15 minutes and seems to really accellerate if I use streaming video or try to upload IMovie to Youtube (more bandwidth?)   This HAS to be fixed or how can anyone work????  I had to race to post this before it crashes again!  SHEESH com&#x27;on Apple!
