It seems the line where it hangs is in '/etc/rc.d/rc.udev':
Code:
echo "Triggering udev events: /sbin/udevtrigger $OPT"
# Call udevtrigger and udevsettle to do the device configuration:
/sbin/udevtrigger $OPT && /sbin/udevsettle --timeout=120
you can read 'man udevtrigger' and 'man udevsettle' to see what they do.
