[QUOTE="fmouse, post: 1340273, member: 228295"] I talked with a senior tech support person at Apple about this problem. He was reasonably clueful, and we discovered that the crash is in the AirPort wi-fi driver, as expected. Connecting the box via an ethernet cable made it go away. He insisted that the cause of the crash was that FaceTime, being a bit of a bandwidth hog, was exceeding the capacity of the wi-fi connection to pass traffic, with unpredictable results. I insisted that a kernel panic was not an appropriate response to this condition, and that if the capacity of a connection is exceeded, the worst that should happen is that the network interface associated with the AirPort wi-fi system goes away and has to be re-negotiated. The behavior I'm seeing (and which others have seen) is consistent with an uncontrolled buffer overrun in the driver, or some such. Anyway, the band-aid for this problem seems to be to use a hardwired ethernet connection rather than the iMac's internal wi-fi. [/QUOTE]
