Minimal MMU linux hangs on DE1 board

Well, finally managed to store filesystem in Flash, now I've much more free memory in my DE1 board. here it is:

nios2-terminal: connected to hardware target using JTAG UART on cable

nios2-terminal: "USB-Blaster [USB 6-1.1]", device 1, instance 0

nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate)
