Right, so my ibook has been open for the last couple days, and so today I had some time to put it back together.
First I tried booting it up with the airport card unplugged. It booted perfectly, no open firmware. So, if as a last resort, we could always just unplug our airport cards . . at the expense of no blue tooth as well :-/
then I cleaned all the little pins and contacts on the card and the logic board connector. Also, I wedged some folded card stock between the little piece that holds the airport card down and the card itself. This adds a bit more tension on the card . . hopefully keeping it in place a bit better.
She booted up beautifully and the wireless came right up with no panic. I updated my adium, left it alone for an hour while I ran over to take care of a situation at work . . came back and she was still not panic attacked :-)
Picked it up (in it's pieced together shape) and shook it, bent it some, applied pressure to all parts of the airport card. Still no panic!
So, finally I went through the process of putting all those screws back in and she is up and running quite nicely.
Who knows how permanent of a fix this is, but this evening at the coffee shop, I was reminded of how much I really missed having my wireless, what a great thing it was :-)

Hope it lasts for quite a while.

Oh, and I put up a couple more pics, showing where I stuck the card stock

Very nice job, imthewa1rus! WE will always remember you as the brave pioneer!!

This is gold for going further to push Apple! People shouldn't have to take their machines apart after 1 week ending of warranty!!

A HUUUUGE roar of approval for imthewa1rus! He ain't just the walrus, He Da Man!

And here's why: Not only did he effectively show that the problem WAS one of poor seating of the card [ and here I briefly pause to meticulously EAT MY WORDS, where I kept insisting that there _had to be_ a separate, firmware related problem ] BUT, he also SHOWED THE ENTIRE WORLD _the smoking gun_; i.e., that little plastic part that fruitlessly tries to hold the Airport Extreme card in place.

Guess what, folks? On my iMac G5 (bought _refurbished_ in Oct 05) _there is NO "reinforcement piece" AT ALL. Which _strongly suggests_ our dear friends at 1 Infinite Loop at some point realized _they had a problem_ where these cards kept _coming loose_, and they _added_/retrofitted the ad hoc "overhead beam".

Which, in turn, suggests they've been PLAYING DUMB for a pretty long while by not making an official appearance on this and other fora to acknowledge what they _rather obviously_ knew.

I feel confident in offerning this analysis because, Yes, Virginia, mi iMac G5 ALS went _back to normal_ after I opened it up, undid the two screws "holding" the card in place, removed it from the connector, then re-seated it _FIRMLY_, put the screws back in, and put the cover back on the machine.

I had the advantage of having an external disk to test with. Once I saw that the machine could once again "see" the Airport card on the test run off the external disk, I was able to put the kext file I had removed back in the extensions folder of the internal drive, do a "disk repair" (using Disk Utility) and after a restart (during which the OS complained of a problem with the kext), do a "repair permissions". Which got me fully back to normal. At Last!

So, once again: Kudos to imthewa1rus, and all sorts of loud boos to the Cupertino crowd.

Here is some helpful information for you mid-2005 Ibook owners
who want to try reseating the panic airport card yourselves.

Thanks for all the kind words Killergull and VeryBadApple. Although, I do not feel they are deserved. :-/
She just started panicing again yesterday.
Royal pain I tell ya. Hope you have better luck than I did.
Was quite nice to have wifi for the few days it works.
And I did used my wifi extensively. between 6-10 hours each day.
Then once as I opened it up, and it woke up . . panic.
I am really really tired of this.

Sorry to hear after all the effort, imthewa1rus.
But I think we all can agree that this problem is all about a loose airport card now. And you were brave and pioneered by testing it out and verified it!!
That's the most important thing!

Apple know this is a design flaw. They had the same problems with earlier Powerbooks/iBooks with better accessable airport cards. An example here:
http://web.mac.com/altero/iWeb/alter...0738B136C.html

That's why the list still is important. Let Apple know that a lot of people get their airport cards loose. Apple should fix this for free (better card seating), and since it also is quite a challenge to try fixing it yourself.

VeryBadApple, how is it going with your iMac? Still free from KPs?

I agree on both of Killergull's main points: the problem is related to poor contact at the "socket" / easily disturbed "seating" on these Airport Extreme cards. Which, by the way, are quite inaccurately described as "non-removable" in the Apple literature (i.e., specs for the PPC iMac G5 ALS). The cards are relatively easy to remove, in the case of the iMacs (not so in the case of the iBooks).

In any case, I'd dare say the cards are poorly engineered. Instead of the diagonal positioning of the screws, which almost automatically creates a potential for the oppostie two corners to bend/twist upward (particularly given the thinness and flexibility of the card's printed circuit board), they would be much better fixed in place with a slot on the "far end of the card" (the one opposite the connector) and the two screws at either side of the card close to or at the connector end.

This way, all four corners would be held, they would still be using just two screws (plus a minor plastic structure to provide the slot on the far end), and the screws would insure that there was even pressure across the length of the connector. Just one pin making poor contact is probably enough to create trouble.

My card is still holding up, even without the "dedicated overhead pressure bridge structure" : - ). BUT, this machine sits indoors all day, and isn't shaken this way and that like a laptop is when being carried from place to place. At most, it gets to slide, table and all, from one room to another. AND the case _is_ really thick and sturdy. I think what triggered the problem in my case was a near-accident when the machine appeared like it was going to fall off the low table on which I keep it, and I stopped it dead in midair. Still, it wasn't anything particularly violent (just a sudden deceleration) and it shouldn't be enough for _supposedly non-removable_, supposedly screwed-on components to start coming loose.

Strength in numbers?

I sincerely hope that Steve & Co. eventually get the message on this, and plan to post my details on the site created by Skinkie (good job there). I discovered this isssue very early on, and recently posted most of the following on the Apple discussion forum before finding you intelligent folks:

****

When it first happened to me last October (exactly two weeks out of the 1-year warranty, of course), I also blamed the recent 10.4.8 update for the issue, but I can tell you all for CERTAIN that the issue is related to the physical properties and design of the Airport/Bluetooth card and its slot. Whether or not it was pushed over the edge by the update is still a matter for some debate.

After a week or so of suffering with seemingly random kernel panics after the 10.4.8 update, I tracked it down in the logs to Airport, and disabling it made the issue go away. But, sometimes the KP would not occur, and would almost never happen when the iBook was on a stable flat surface. After some experimenting, I found I could make it crash consistently by picking the Airport-enabled iBook up and moving it around, especially if it was being held by the left-hand front corner, which I guessed was making the motherboard flex.

So, as an old electronics technician who spent many years repairing gear at the component level, I went to the bench and got out the tools.

After a successful search for some disassembly info, I took the iBook apart (Please note: this is NOT recommended for inexperienced persons, it is not a simple task even for someone with these skills). I then found the Airport/Bluetooth card (in exactly the idiotic location that Apple decided would be better somehow than the accessible location where they USED to put it). It had clearly worked its way partly out of its slot, and I pushed it back it again.

Long story short: no more problems for a very long time, about 4 months, even when moving around with it, using it on my lap, in the car, etc.

Just last week, however, I had the same problem again, when I happened to pick up the iBook by its left front corner again, and immediately got the KP, the same log entries reported here and elsewhere, etc.

So, it's now time to open the thing up again and re-seat that card. This time I am considering Superglue...

My theory is that it is happening after a certain number of cycles of heating up and cooling down that results in the circuit board "creep" that causes the problem, and is likely made worse by the bouncing and jostling that laptops are subject to. Mine goes in and out of the house every day in its wheeled case, rides around with me in the car, in and out of buildings and classrooms, etc. Typical road warrior use.

This has been going on with enough documented incidents for several months to constitute a problem - where are the Apple reps? Hiding, looks like.

By the way, I am a school district IT director by profession. I plan to stand up at the next Apple update meeting for us educational IT-types and ask in a crowded room why Apple hasn't recognized or admitted they have a design flaw that needs to be corrected. Lots of schools have these units, and must be running into the issue.

I often ask these guys hard questions like that just to see them scramble...

****

After posting this epistle on the Apple discussion forum, I sent out a message to two lists I am on for school tech directors in two states, warning them and describing this widespread issue. Strength in numbers, and we do get to meet with Apple corporate types at least twice per year. I think a recall program is not too much to ask, but all of these outfits (Apple, Dell, etc.) seem to only react when they hear the lawyers warning up in the bull pen.

Back from holiday

After I came back from my holiday I checked the forum and saw the 'fix'. Now I was still in warranty and they 'said' they had to replace my complete logic board. I got my laptop back today, and I think I should be happy that it doesn't panic anymore

Ok, folks. What do we do with the list now? Now when we now what causing the airport panic, where will the list do the most impact so Apple most likely will react?

I relate with VeryBadApple. I have the same computer that he does, and I bought it at the same time. AirPort worked fine, until I moved. It hasn't work since. Kernel panics all around, you know the story.

Due to this forum, I can safely assume that during my move, I loosened my AirPort card. I am going to attempt "the fix". But I sure would like Apple to do it for me.

Come on Apple, you know there is a problem here!

Well, noting that this thread has 230 posts and almost 12,000 views -- it’s certainly caught the attention of somebody!

I'm not posting any new information, just want to add to the number of complaints.

My G4 1.33 ibook (refurb 10/28/2005) just began KP'ing this weekend. Same Airport messages in the panic.log. Currently I can't boot beyond the gray apple screen -- not even into SU mode. I've repaired hardware on apple notebooks many times in the past. But replacing the entire logic board is way beyond cost-effective.

When mine was repaired, they did not replace the logicboard; i'm not sure exactly where but somewhere on or around the airport card the technician found dry solder, which had consequently cracked and caused all my problems. So if anyone has their iBook at the ready to open it up, please, take a look around the logicboard and in particular the workings of the airport card to see if this is the problem (note the problem could have been on the airport board itself; so you may need to see if its possible to take the protective case around the card off).

Another iBook nightmare

Just wanted to add my story to this page;
My computer: late 2005 iBook, 1.33 Ghz PowerPC G4 with 1.5 GB DDR SDRAM which I purchased in Sept 2005.

Almost exactly a year to the day after purchasing it (i think it was 4 days past a year if my memory serves me correctly) the computer went into a dreaded KP directly after installing the 10.4.8 software upadate....AWESOME!!! Immediate restarts generated a black screen, so at first i thought it was something to do with the video card. The normal PMU, PRAM and NVRAM resets would work, but only sometimes, often requiring me to perform them 10, 15 times in a row to get it to boot. I finally used a safe-boot hot-key and disabled the airport card, and frantically went to work backing up my files. I wiped the drive, zero-indexed and re-installed 10.4.....more KP's and still no airport card!!!!! I tried everything again after this, including a hardware test, permission repairs blah blah blah.

That brings me to now....a year later and i basically cant shut my computer down EVER, without the hastle of sitting there for an hour trying to get it to boot. If i do have to shut it down, i use force-boot osx (restart+X). That seems to boot everytime with no hassles.

Here's the BEST PART; a friend of mine recently came to stay with me, and he just happens to be a certified apple technician working in NYC. So of course i have him look over my situation....two hours later, and alot of head scratching, he ends up on the phone with an apple guy, pretending to be me (watching him act dumb was amazing)......the apple guy ends up telling him that the computer needs a new logic board and its not covered under applecare.

To make things even better, about 4 months after purchasing my iBook, i suggested to my sister she look into buying one. She did....and guess what??? One year later THE EXACT SAME THING IS HAPPENING IN HER IBOOK!!!!

Just a final note to the "people" from Apple computers, if they actually ever read these things....im not a rich man, actually im quite poor, certainly by the poverty standards set by my country (Canada). Spending almost $2000 on a laptop was a really BIG DEAL to a Joe Blow like me....and to be told in the end that i have to spend another $600 to "fix" my laptop is completely insane, considering your company is responsible for putting a product on the market that was defective from the beginning, and currently unable to admit to the mistake.

It will be really, really difficult to convince myself to spend my hard earned money on another one of your products in the future.

Exclamation airport woes

just wanted to throw myself into the fray by saying i am in panic city

if i turn on airport the thing freezes and then we get the panic and sometimes, after a pmu reset, a lovely firmware screen. anyway it is a mid 05 g4 ibook and i would love to know how to fix it. of course i'd LOVE to down load that 22 meg manual but my airport is kinda crashed. 56k all the way

thanks

I called Apple again today and was told that they have no knowledge of any sort of "emerging issue" with all this. I was told again that I could pay $300 for logicboard repair or $60 to get a new install disk (I lost mine in a move). Other than that, the guy had no solutions.

Hi, I have an iBook I bought in October of 05 and sometime in February I started experiencing the same kernel panics. Same error, same symptoms. I finally had enoug of using a direct firewire connection to my PC and attempted the scary "iBook Airport wedge cardstock under the bar" operation. Everything went smooth, and I booted up my machine. It worked great for about 5 minutes and then... BAM! kernel panic.

So I'm stuck again, but I wanted to add my voice to the crowd. I hope Apple takes care of us...
