Based on the Apple Discussion Forums, I see I'm not the only one suffering from this phenomenon. I consistently get Kernel Panics while using Skype and my Bluetooth headset. It doesn't seem to be Skype related as the culprit appears to be the A2DP driver (IOBluetoothA2DPAudioDriver). It seems to happen just as consistently when using the headset for any type of audio. I use Skype a lot for work and it's getting to be a real issue. I can reproduce this on 3 different systems (Powerbook G4, MacBook Pro, Mac Mini), however, I suffer no problems on my Hackintosh (Dell Dimension 5150 running 10.5.4) I use a D-Link DBT-120 USB Bluetooth adapter that is recognized natively by OS X. How many of you out there use a Bluetooth headset for audio output? Are you having any issues?
