Hello;
I have a 43P 150, that does the same thing. it is not your
netbooting, it is the kernel that does not boot. Some people said to me
that it was a bootloader problem, (mine crashes exactly the same point)
but noone was able to find a solution.
What did you type to boot from the network in the boot prom?
