I have very bad experience with bootload and setting console parameters. I am
using 7260, and there is a hardware support for selecting different serial
ports as a console. But, certain combinations of this jumper together with
"console=..." setting made kernel freeze. It did however answer to ping from my
host machine.
Try to remove "console=/dev/ttyAM0,115200" part of parameter and see if it
helps. You can test with ping to see if you have the same problem as I had.
Seems to me that kernel gets stuck writing to console buffer, which never gets
emptied for some reason.
