A kernel panic is an OS X error message that appears, telling you that you need to restart your Macintosh (in several languages). See: http://docs.info.apple.com/article.html?artnum=106227 Though a kernel panic can be caused by a software problem, it is much more often caused by a hardware problem. Usually bad RAM (usually third party RAM) or a bad USB hub or USB device. Have you installed more RAM, or added a USB peripheral, recently? Remove them and see if things clear up.
