Sorry if i am hijacking the post, but when you say kernel panic you mean the classic freeze of the computer? Where you need to hold down the power button to restart your machine? Sorry but I know in reality what is a kernel panic but I don't know if this is what you mean when you are posting in these forums.
Apart from this, I think I had my first kernel panic yesterday . I don't think it's due hardware issues, however it seems it has to do something with the dynamic switching of graphics card. I had opened at the same time Photoshop, Illustrator , Dreamweaver and the new firefox . When I closed firefox upon the switch of gpus the computer freezed. Don't know if this is related to your post
