I've played around with this quite a bit. There are several pieces to
this puzzle. If I missed something, let me know and I'll try to fill in
the blanks. Doesn't seem to matter which version of u-boot or firmware I
use, the boot always fails. The most common way is shown below with the
looping gen_intr2 message. The other common way is that genet0 isn't
found after the kernel is loaded. Here is the general setup of my
netboot server ...
