Kernel Panics since 10.4.4 - can you check my panic log?

[Project]

Well ive just spent the past 3 hours trying to figure out exactly what went wrong with my iBook, but it was Kernel Panicing like crazy. I couldnt even get online long enough to make a post about it.
Lets recap.

I updated to 10.4.4
Several hours later the Mac crashes for the first time since I switched 3 months ago.
It crashes again.
Kernel panic!
More kernel panics!
So as soon as I logged in, I created a dummy account then rebooted with it. The dummy account would crash too so I knew that it was a system problem. This leads me to believe it was 10.4.4
I did an archive and install.
No luck

Any thoughts? I have not installed any hardware. Its as it was prebuilt. It cant be a hardware problem.

I installed shapeshifter several weeks ago and uninstalled it about 4 days ago.
I did repair permissions after updating.

HEres the log. I notice Airport in there....

Boot to single user mode. Run fsck.

Don't be fooled by the Airport message. The panic occured while a network operation was taking place, but that doesn't mean it was the cause of the panic. As you'd expect, network operations take place all the time.

Fall back to 10.4.3 and see if the problem persists. If so, there's probably a bug in 10.4.4. There's another thread here from a fellow in New Zealand. He's having kernel panics with his iMac G5, and the evidence in that case also points to 10.4.4 problems. (although it could also be hardware in his case)

Ever since replacing the bad RAM i had, all my kernal Panics stopped....until I installed shape shifter...then I had one


After trashing every possible thing associated with Shape Shifter the Panic is no more.

Just a thought, maybe you missed a .plist file for shapeshifter?

Well, just to update you, I ran every check. fsck, hardware test, single user mode etc. Still the same. So I backed up and did a clean install. Kept it at 10.4.2

Now im having CRAZY problems. Sometimes it doesnt recognise I have an airport installed. Then it freezes up after about 5 minutes of use. I cant type, move the trackpad etc. I plugged in my mighty mouse and that wouldnt scroll either. I noticed that the airport reception meter in the menu bar would blank out at the same time to inidicate no networks. Strange. Rebooted and it would make the chime but not come on. Yet the keyboard light works so the power is definitely on.

Went through this process a couple of times. Then just switched off airport. So far so good, as its allowing me to type this. Theres a number of articles on the Apple support site that speaks of incorrectly seated Airports causign this kind of thing.

I will be taking it to the Apple store in the morning to get it sorted. I highly suspect that its the airport card not properly seated, or something to that effect. I havent a clue how to get to the Airport card and dont want to mess it up, so the store is the best best. I bought it from the online store though, so im worried they wont do anything. And if they do, it would mean being without my laptop for weeks. Anybody have any experience of the repair process for built-to-order machines?

Nah, it's incredibly easy to reseat the card yourself. Here are the instructions:

Basically, flip the keyboard over, pull the card out, push it back in. Really really simple. Give it a shot!

That article is old. The latest iBooks have the airport card UNDER the motherboard. I took it in and they are going to have to take my iBook apart to get to it. Could be without it for 10 days. I am resigned to a PC for the moment No expose!

Are you serious? What a terrible change for Apple to make! One of the few knocks on Apple notebooks is that they aren't designed to easily upgrade certain components (hard drive especially), and this only makes it worse. Bad Apple!

Bummer.

Thanks for the update. Do let us know what the Apple Store finds.

Well I just got my iBook back. The receipt says new Airport Extreme card, new Logic Board and labour. Total cost £450 ($750)

Luckily, under warranty so it didnt cost a penny. But I am now SERIOUSLY considering getting Applecare.

That's a good idea.

You'll want to beat your own head in with a rock if you have display problems after your warranty runs out.

To be honest, considering Applecare is pretty expensive, I may just sell my iBook in a few months, hopefully getting 50% of what I paid for it, then buying a new Intel iBook. Considering that I would then have an extra years warranty as its a new product, plus a much better machine, I think its a better option.

Option1
Buy Applecare £149
Total cost = £149


Option2
Sell iBook (£350)
New Intel iBook £615 (student discount)
Total cost = £265

Hmm, it would make sense to do this EVERY year, keeping the Mac in warranty, bang up to date, at a cost of only £265 a year. lol.

i haven't been getting as many kernel panics but i have gotten a few and i always force quiting mail and just in general my computer as been running like dog crap

I get these kinds of panics when I use my mac as a wireless access point-- I'm using my airport card to "share" my ethernet-based internet connection. Seems to be load-related--if I only have a handful of users sharing, no problem; if I have a couple of dozen, my mac hangs about once an hour (and shows a similar kernel backtrace when I power-cycle).
