I've got an old iBook G4, 14"/1.42 GHz/Tiger
It has the kernel panic problem when AirPort is on. When setting AirPort off, the computer works for hours and hours.
For my surprise, setting Bluetooth on allows me to work in internet without problems (via iPhone). I have understood that both Bluetooth and AirPort are taken care by the same internal card - am I right?
Apparently my problem is in Card and not in the connection/ motherboard connector?
