It definitely says: "[ 1951.095382] f02969dc: ttyS0 at I/O 0x0 (irq = 1, base_baud = 115200) is a SUN4V HCONS^M" So just passing "console=ttyS0 keep_bootcon" has to work. If it doesn't, there might be something incorrectly configured with the hardware. There isn't really anything else that needs to be done to get a serial console. Adrian -- .''`.
