I do not know for the wifi part, but using a webcam on a multicore system (here a i7 980X) with any of cheese, gmail+ video plugins in mozilla, or even skype, ends up with first some locking in the video+audio/
It does not happen on true monocore system (here a old AMD 3500+).
Looks like the webcam driver (if any) has a concurrency issue with something in the kernel. It might ends up corrupting the wifi part in the way to the total destruction of the kernel data.
