Argh! I have been getting weird kernel panics and freezes for the last couple of days on my TiBook, aftering installing the latest patch to plug a security problem relating to cookies for Safari, althou there is no reason to suspect that this patch has anything to do with it.
I get kernel panics now and then before, but normal together with the reboot message. First time my Tibook was stone dead.
PITA.
Update (17:03): Argh… I was trying to fix the problem by booting from the installation disk and do a fsck disk. Somehow the combo drive ejected a CD then refused to take another one. Good thing I bought the AppleCare extended warranty. Backups are up-to-date. Phone call to Apple first thing Monday morning. I am already suffering withdrawal symptoms.
