My new 1.67 15" PowerBook (superdrive) boots just fine off of the install CD that came with it, but if I try to boot off of any other bootable CD, it will kernel panic. No attached peripherals when trying to boot off the CD either. I have reset the PRAM, run FSCK, repaired permissions and disk while booting from the install CD. Still panics...no change. I've run ToolTech Pro, as well as the Apple hardware test, and everything appears to be in order. I'm thinking this is probably a software issue, but I really don't want to have to do a reinstall of the operating system just yet...I just got it a week ago and I'd really hate to have to start over with installing everything. I just want to make sure that this isn't a hardware issue (if it is, I can exchange this PowerBook for another). Anybody else having this problem?
