My 10.8 system always hangs at "still waiting for root device" when not using the -x option. When using it, it boots without problems.
The system is a Dell L702x.
The message directly before "still waiting for root device" comes up is "USBMSC identifier (no-unique).
This is a list of the kexts I got, can anyone spot which kext is producing the problems? http://pastebin.com/E3n4cwJE
Edit: Fixed, can be closed.
