I've lost some of the context on the board you are working with, but from ttyAMA2, I'm assuming it is an arm board. Have you verified that your bootloader can pass the kernel bootline properly to the kernel ? It is (unfortunately) fairly common that it isn't properly passed. If you modify your configuration to have a built in command line with your configuration, you may be able to get better setup to debug the problem.
