linux socfpga 4.9 stops at bootconsole [early0] disabled

I built linux from altera's github and loaded the file vmlinux (it didn't work to load the /arch/nios2/boot/vmImage).  

 

I see the following at the console and I want to know why it stops.

Ok, it was the kernel command line I had to select "Passed kernel command line from u-boot"

Now I get kernel panic because of filesystem instead.
