When I'm watching web videos, downloading an iTunes purchase, using Airplay, or downloading a Bit Torrent I get Kernel Panics. I am using a Late 2009 i7 2.8ghz 27" iMac and 8gb of RAM. I called Apple support and they suggested I could be getting malformed packets from my router since all this stuff is happening when I use the web. So I flashed my firmware on my Belkin N router but it's pretty much still happening. Do I need another router? This didn't happen in Snow Leopard and doesn't happen on my girlfriend's i5 Macbook Pro which is running Snow Leopard... Any advice? Like seriously it's like running a 1998 PC.
