My iMac had a kernel panic attack. I was running Google Chrome with about 10+ tabs opened and iTunes. There hasn't been any hardware changes. I also have an external drive connected to it via usb. I have Bootcamp and another drive (Macintosh HD 2).
Mac OS X version 10.7.1 2.7 GHz Intel Core i5 4 GB 1333 MHz DDR3 AMD Radeon HD 6770M 512 M
What I remember reading from the report send to Apple was something about ATI Radeon I think. So I guess it's a hardware issue? I hope all this info helps, thanks.

iMacs are notorious with heat issues. Especially ATI graphics. Update the graphics driver if it isn't already. Also the iMac need to be sitting away from the wall, like a inch or so. I wouldn't sit anything behind it, as in your external HDD.
