Finally I accomplished something that is worth to make an Instructable about :-)
You are probably here because your good'ol iBook started acting weird after the update from Mac OS 10.4.8 to 10.4.9. In the manner that you allways get kernel panics (KPs) when you try to work with activated Airport-WIFI. For some people only when working on battery, for others all the Time.
In my case the notebook even sometimes refused to reboot after a KP and I had to leave it for about 15 minutes to cool down. But it definitively KP'd as soon as I switched Airport on.
I tried the widely distributed "paper-patch" where a folded piece of paper is put on top of the airport card, under its plastic holder to tighten its seating even more - with little effect. It only accomplished that I now could work for about half an hour before it KP'd again.
So hence the reason seemed to be a loose connection between the card and the mainboard (which the driver before the 10.4.9 handled flawless) and the connection between card and socket was tightened as it could be - more drastic measures had to be taken:
Once again I took the whole frickin' thing apart completely and this time removed also the mainboard to have total access to it from all sides. Since the socket is made of plastic, a hot-air reflow was out of question.
So - I manually resoldered all those tiny (ca. 0.3mm each) pins with the smallest tip in my soldering iron which i acuminated even more with sandpaper. And what can I say - after putting it back together, I started it up and loaded several ISO-images over the Airport-connection for hours and put it in standby once in a while.
It works perfectly now :-). No KP whatsoever since the repair. Not the tiniest hickup - the problem is completely gone!
Step 1: Preparation
- How to work inside computers and what has to be taken in account when doing so.
- What electrostatic charges are - and how to avoid the damage they can do.
- How to solder and if you have a steady enough hand for this.
- How much heat can be inflicted on circuit boards and small electronic components.
- And last but not least if you are able to take this thing apart and put it back together.
When you can answer all of those with a yes, go ahead :-) - If not - you should better retreat until you can - before you have a completely broken unit afterwards.
