Can't boot without -x

[expertmac2]

Hi,

 

I've installed Mac OS X Leopard using iATKOS 5i on a Dell Inspiron 6400. I've installed some kexts too, and I think one of them is hanging the boot. My problem is that whenever i don't give the flag -x on bootup, it crashes after this message:

 

Dec 17 15:47:20 localhost mDNSResponder[39]: WARNING: sandbox_init error

service com.apple.bsd.dirhelper err=1100
Could not set Mach lookup policy for service com.apple.SecurityServer 
err=1100Could not set Mach lookup policy for service 
com.apple.SystemConfiguration.configd er

]

 

Plus, if I wait awhile, the OS X GUI Cursor pops up and has a spinning wheel of colours, which means its busy. After that, it enters a hanging boot up thingy, where it doesn't make anymore messages, the cursor still spins, and the mouse pad is active, so I can move that wheel cursor.

 

(The cursor is really on the screen when I boot with -v!)
