Yes, the warning means that there's no RTC on the RPi...

When things hang after this message it usually means that something is wrong with the driver for the root device. The best way to track this down is to change the root device and see if it persists. You can also make sysinit verbose, which also helps track things down, at the expense of a lot of spew on boot.
