I get a message saying "You must restart your computer." (hold down the power key, blah blah). I've researched a little bit, and apparently its indicative of a kernel panic. I cannot get it to go past this point. HELP ME (please, I'm stressing out over here!!). It's not booting from CD either.... what's going on? (This happened for the first time after I installed the latest updates [for 10.4]) Thanks in advance for any suggestions!!
