I'm having trouble with my kext with Safe Boot Mode. I have the kext set with Local-Root, but I'm not able to boot reliably in Safe Boot mode. The kext is a disk driver that must load at boot time for the boot disk to operate properly. One way to make sure your kext is properly set up is to make sure it is being included in the mkext. /usr/sbin/mkextunpack will let you see what's inside your mkext. I've gotten safe boot mode to work when booting from an internal disk to Tiger with my kext. But I have not been able to get Safe Boot to work with Leopard. When booting into Leopard it appears to eventually time out and restart. One possibility is that you link (via OSBundleLibraries) or otherwise depend on something that isn't marked Local-Root on Leopard. I assume your kext works fine on Leopard when not safe booting. It's difficult to debug as two machine debugging appears to be disabled as well as verbose mode. I don't know what the debugging rules are during SafeBoot, but you might be able to enable FireWire Debugging (much simpler in Leopard). Suggestions? There's always "rebooting your way to success:" put a panic into your driver's start() routine to find out whether it's even getting called. :) This email sent to site_archiver@lists.apple.com
