Happened twice today.

What sucks about MacOSX troubleshooting is that you I feel like a total n00b. On Windows I knew how to fix things and a crash like this happened maybe once or twice in four (4!) years with my laptop's XP (Professional install). I am not even sure if it happened really twice, I am pretty sure it only crashed once. Yeah, I know, I am a lucky bastard but what can I say. Also, my XP-install is four years old! It's the IBM install that came with my nifty X40.

Anyway, back to the crash:

(Summary in case the link stops working: Disable IPv6 on your Airport in System Preferences > Network > Airport > Advanced > TCP/IP)

Not sure why I had IPv6 in there to begin with. But now it's off! IPVv6 is dead anyway (sorry, I could not resist).
