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. :)
