linux socfpga 4.9 stops at bootconsole [early0] disabled

[Altera_Forum]

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.   Linux version 4.9.0-00104-g84d4f8a-dirty (developer@1604) (gcc version 6.2.0 (Sourcery CodeBench Lite 2016.11-32) )# 10 Tue Apr 4 11:38:13 CEST 2017 bootconsole enabled early_console initialized at 0xe8001400 On node 0 totalpages: 32768 free_area_init_node: node 0, pgdat c02216ec, node_mem_map c0254b80 Normal zone: 256 pages used for memmap Normal zone: 0 pages reserved Normal zone: 32768 pages, LIFO batch:7 pcpu-alloc: s0 r0 d32768 u32768 alloc=1*32768 pcpu-alloc: 0 Built 1 zonelists in Zone order, mobility grouping on.
